How Much Power Can You Get from Solar Roofing Panels? All The Data You Need To Know 2022

The US Energy Information Agency has estimated that the average U.S. household uses 11,000 Kwh per year or about 30 Kwh per day.

Solar Panel Output

How much power can you get from solar roofing panels? This will depend on the efficiency of the panel’s solar photovoltaic (PV) cells in converting solar light energy into electrical energy.

The efficiency of a panel is defined by a complicated formula that assumes optimal sun exposure. An 8% efficient panel will require twice the area of a 16% efficient panel to produce the same output.

Although, we often hear of marvelous advances in solar cell technology in the laboratory, the commercial solar cells available today represent the current state of the art.

Commercial solar roof panels average 14% efficiency and produce about 14.4-w/sq ft (155 w/sq m). Standard solar roof panel sizes are about 13.5 sq ft., and each panel produces about 200 watts. Wholesale prices for these panels average about $1 per watt.

Is That What You Get?

That is a lot of power if you can utilize it cost effectively. Actual panel power output will depend on your homes geographical location, roof orientation and the chosen solar power system. Is your goal a completely off-grid system that fulfills all your electrical energy needs, or is your goal a grid-tie system to decrease energy bills?

The amount of yearly sunlight available across the continental U.S. averages about 5 hours. The northeast sees only 4.2 hours of full sun, but the southwest enjoys 5.5 hours. Assuming an average of 5 hours of sunlight, a 200-watt panel would produce 1 Kwh/day or 365 Kwh/year. Panels sell for about sunlight.

Solar System Type

For an off-grid system, a Derate Factor must be included that adjusts for the efficiency of an off-grid solar power system in transferring panel output to your home outlet. A common value used is 0.77. Therefore, a 200-watt panel will ultimately produce only 154 watts – 281 Kwh/year.

In a grid-tied solar power system simpler set-up, power goes straight to your utility meter. The power generated from your solar panels goes into the energy grid and offsets the cost of power you use during sunless hours. With this direct connection, a grid-tied system does not suffer from this loss.

Costs

Assuming your home uses the U.S. average of 11000 Kwh/year, an off-grid system would require 40 panels spread over 540 sq ft of optimally oriented roof space. Cost for panels would be about $7800. With an off-grid system, you would need inverters to convert the power to AC and batteries for storage. A complete off-grid system could easily cost $20,000.

A grid-tie system would only require 30 panels. With an inverter to connect to the grid, a grid-tie system would cost about $12,000 and – in theory – totally offset your energy bill. However, a grid-tie system can be scaled down to only offset a portion of utility costs.

According to the US Energy Information Agency, the current average price of electricity is about 11.3 cents per Kwh resulting in a monthly bill of $103.67 or $1,244.04/yr. However, the variation in cost of electricity by location is greater than for the hours of sunlight and may be a more important variable.

The necessity for government incentives probably shows that solar energy simply has not reached the ROIs making them practical for the majority of homeowners.

Should You Go For Solar Shingles? The Photovoltaic Cells That Resemble Traditional Roofing Bricks: Everything You Need To Know 2022

Solar shingles are photovoltaic cells that are designed to resemble conventional asphalt roofing shingles. They not only look like roofing shingles when they are properly installed, they also perform like roofing shingles.

They are completely weatherproof and have the advantage of being able to produce electricity. Solar shingles are completely eco-friendly; they do not radiate heat, make noise, or emit greenhouse gases.

The Appearance

Many people would like to utilize solar energy to reduce their energy expenses but hesitate to add solar panels to their roofs for two main reasons. The first reason is appearance. The large panels are unsightly and detract from the overall aesthetics of the house and garden.

The other main reason is the way they are installed. The roof envelope needs to be pierced to bolt the panels to the structure, which could allow water to leak through the roof and compromise its effectiveness.

Solar shingles are installed in the same manner and with the same tools as regular roof shingles. They are weatherproof and provide excellent protection. The color blends with regular asphalt tiles, but even if the color is different, it does not detract from the beauty of the house as much as a traditional solar panel would.

Profiled solar shingles are being developed that fit exactly with regular profiled shingles. Today, the S-shaped profile shingle is available. It is flexible, durable, and recyclable.

The solar shingles are connected to the ones on either side and in this way they are all connected to an inverter placed inside the home by a licensed electrician. This changes the electricity from DC to AC, which makes it useable for traditional appliances.

The Cost

Solar shingles will lower the electricity bill of any house, but the savings for an individual homeowner will depend on the cost of electricity in their area. The house will still be connected to the existing power lines, which will work if there is not enough light to power the shingles.

On the days more electricity is produced than the residents use, the balance can be sold back to the utility company for credits in 39 states. There are specialized solar shingles being produced for places in the north that don’t have as much sunshine as places in the south.

Solar shingles do not need direct sunlight to produce electricity, they only need daylight. This is a big boost for cloudy days.

Because of the Energy Policy Act of 2005, there are generous federal tax breaks for installing solar power. The initial installation cost can also be rolled into a mortgage in most cases. Even before tax breaks were given, the cost of installing solar energy was reducing every year.

The initial cost of installing solar shingles could be anywhere from $15,000 to $20,000. Local, state, and federal incentives can reduce the cost by up to half.

Added to this, the electricity bills will be reduced by 40 to 60 percent. With the rising cost of electricity, homes that have a substantial number of solar shingles will greatly increase in value.

Solar shingles allow homeowners to take control of their utility bills. Whether they are supplying half of the electricity needed or supplying much more than can be used, the electricity bill will be greatly reduced.

This alone is enough incentive to install solar shingles, but with the federal tax credits and state and local utility discounts, the potential savings over the years is substantial.

Power Source Options For Off-Grid Cabins: Alternative Renewable Energy For self-Sufficiency 2022

It’s becoming more and more common in today’s technologically advanced society for people to gravitate towards a lifestyle set in nature–one that doesn’t depend on the rest of the world for any day to day needs.

Known as off-grid living, this back-to-basics way of life is not only independent–it’s earth-friendly as well. Off-grid cabins that have power don’t get it from utility companies–they’re powered by green power sources that conserve energy and in the long run, save money as well.

If you’re wondering how you can get your own power in an off-grid cabin, read on. Featured below are three excellent off-grid power source options.

Hydropower

Hydropower is a very green source of power, as long as you have a continually flowing water source such as a river, creek, or stream on or near your property. A hydropower system takes water run-off from a dam and uses a turbine to change that water into usable energy.

Once the falling water spins through the blades of the turbine, the usable energy is carried into your home via a generator. You need free access to a moving water source in order for hydropower to power-up your cabin, so it’s important to check with your local DNR before investing any time or money into a hydropower system.

Solar Power

Solar power is the most popular power source for off-grid cabins. Unlike water, there’s no regulations placed on sunshine–and it’s almost always readily available regardless of where you live. To get solar power in your cabin, you must install a system that consists of solar panels, batteries, and an inverter.

A fairly large system is required if you want to be able to use large appliances–and while the initial investment might seem rather hefty, it is a system that will save you a lot of money down the road. Solar panels capture sunlight in special cells known as photovoltaic cells.

The solar panel system then transforms the absorbed light into energy for your cabin. There are many systems available if you want to use solar power, so it’s important to figure out what you need and compare all of your options before you decide which system would be the best one for your cabin.

Wind

Another option for powering an off-grid cabin is wind power. Wind is turned into usable energy in a fashion that’s similar to hydropower systems–only using wind instead of water. The turbine rotors of a windmill or wind tower spin as wind passes through them.

This rapidly moving energy then enters into a generator that is situated inside the wind tower. From there it goes through the power lines and into your cabin.

Wind towers work great providing there’s enough wind to keep them going–they’re efficient and cheap once the initial investment is paid off.

The location and size of your cabin, along with the amount of power you expect you’ll need are the main factors you should consider if you’re trying to determine the best power source option for living off-grid.

While one may be a better option for your situation than another, any of these options will save you money and allow you to live free and green.

How To Brighten Your Landscape With Solar Powered Decor – Follow These Steps For The Easiest Outdoor Revamp 2022

Solar power is the greenest, most efficient, and now the most beautiful way to decorate outdoor landscapes. There are many different styles of solar-powered lighting fixtures available for your outdoor living spaces.

With options ranging from traditional garden stakes equipped with LED solar lighting to lights embedded in artificial rocks that blend into your walkway, you can easily find a style that fits into your landscaping design while using solar energy to power the design.

Combination of Tradition and Art – Many homeowners maybe only get to experience half of their lovely gardens due to a lack of Art decorations. That’s where kettle solar garden lights come in: The light is like a waterfall, adding a touch of beauty and atmosphere to a yard while also providing essential lighting.

Choosing Your Landscaping Decor

Choosing solar-powered landscaping decor is a flexible way to light your outdoors. Since you don’t have to worry about wiring limitations, you can choose from many different types of styles that fit well into each space you are landscaping.

For instance, a family of owls can adorn the lighting fixture you choose for whimsical garden decoration, or you may prefer a simple stainless steel lighting cone that provides a neutral lighting option that won’t interfere with other decorations you have in the area.

Mixing and matching are a good idea if you have a large space for light. Using a fun lighting fixture near benches or tables provides you with a conversation piece, while traditional garden stake lighting is used along paths and walkways without interfering with your overall landscaping design.

Integrating the lighting in your design is also recommended, especially if you are just getting started on the project. Ideally, solar-powered lights should be used about every six to eight feet along walkways for ideal lighting.

Creating A Design

Lighting your landscape with solar-powered decor is very simple. The lighting is very similar to traditional electricity-powered lights. The only difference between solar power and electric garden lighting is that you don’t have to rely on wires and switches for the lights to work.

Most landscaping design architects recommend using a focal point in each area, with other lighting being functional and not decorative.

One simple way to create a beautiful outdoor living space is to opt for one unique lighting piece and simple, efficient lighting for the rest of the area you are designing. It is also advisable to decide beforehand where your focal points will be.

For example, you may decide on using a focal piece in both the front and back lawns. You can also design a special area, such as the flower garden, separately from the rest of your property. Creating a theme for your entire property can really work to bring the theme together.

Using the same basic, stake-style lighting throughout the property works to unify your theme, while focal points set each area apart. Focal points can also follow a theme.

For instance, you may choose animals, pets or even be more specific and use dogs or cats holding a lantern. Whether you choose fun or traditional lighting fixtures, solar lighting is very easy to care for.

Care And Maintenance

Most solar outdoor lights use LED bulbs. This type of bulb is very long-lasting, often burning for many years before being replaced. The batteries used can vary depending on the brand that you purchase and the style of the fixture.

Lights that use rechargeable nickel-cadmium batteries generally last for two years of regular use. Some companies recommend that you turn your solar lights off once a week to allow the batteries to completely charge.

Leaving your lights off for a couple of days a week allows the batteries to fully recharge and can add an extra year or so to the life of the batteries in the fixture.

You may also want to consider the weather in your area when choosing lighting fixtures. Some solar lights are decorated with glass, for instance. Glass can crack or break during very cold weather.

If you live in colder temperatures, you can choose a different material for your outdoor lighting to ensure it lasts or you can simply store your outdoor lights during the cold season. With proper care and maintenance, your solar-powered decor can last for several years.

A Sunny Proposition: Top 3 Considerations To Think Over Before Going Solar At Home 2022

The sun offers one the largest sources of potential energy on the planet. As technology marches forward, we are able to harness its power with increasing efficiency. Solar energy was an expensive switch to make when the associated technologies were in their infancy.

However, solar power is beginning to flood the market. It is now affordable, and the options for use are diverse. Most homeowners understand that they will basically be using large panel units to collect the energy from the sun. From there, however, most individuals are in the dark when it comes to evaluating the solar potential in their very backyards.

Estimate The Amount Of Day Light

The first step is to estimate the amount of sun that your property receives on a daily basis. Houses that are facing south tend to receive more intense sun throughout the day. In many counties, customers can log onto a website to check the actual solar index for the property that they own.

The intensity and amount of sunlight your home receives can help determine the size of the solar panel that you should consider. Once you have this estimation in hand, it is time to do a little math.

Determining just how long it will be before you see any actual savings based on your investment can be done by visiting http://www.consumerenergycenter.org/renewables/estimator.

Incentives and rebates offered by state and local governments can also play a huge role in saving you money on your investment. The programs are not permanent and tend to fluctuate based on location and other factors. Visiting http://www.dsireusa.org can give you an idea of the kinds of savings available to you.

To Own Or Not To Own Solar Panels?

The next decision involves the panels themselves. There are now leasing options available to homeowners. Although prices in panels have dropped dramatically over the past decade, the installation can still cost nearly $20,000 for the average home. Leasing avoids this huge upfront expense.

You will not own the system, but the benefits to be seen in the monthly electricity bill will certainly offset the cost. After you have made all of these decisions, it will be time to shop for a contractor to install the panels. Installation can certainly be done by the homeowner.

However, the panels tie into the electrical systems of the home, they are heavy, and the internal mechanisms are complex. Installation by a professional is highly recommended. If you are renting the solar panels, then the company will insist that a professional contractor install the system.

The contractor that you use should be licensed. The rebates and other incentives that you may be planning on taking advantage of will only apply when a licensed contractor is used or the homeowner completes the installation. Any doubts about the validity of a contractor can be cross-referenced by checking them out at http://www.cslb.ca.gov.

A Scalable Resource

The above tips apply to homeowners that are planning on switching to solar power with full steam ahead. Solar power is scalable, however. Purchasing small panels and towers for use specifically on patios or in gardens is certainly an option as well.

Every little break in the electricity bill helps. These types of areas may be the only place where there is adequate sun on many properties. These units are inexpensive, easy to install, and can generally be wired to work with any type of electrical device.

What Is LEED Certification? Regulating Green Design And Construction From The Top Down 2022

LEED certification (Leadership in Energy and Environmental Design) is an invaluable asset to any new construction project.  This building rating system standardizes the characteristics of buildings that ensure it is efficient, environmentally friendly, and provide a safe atmosphere for employees or residents. 

This independently applied certification was developed by the United States Green Building Council but is now being put into practice across the entire globe.  Buildings that score well within this system use green products and technology from the roof down to the individual nails. 

High ratings increase property value, lessen the total costs of construction, and reduce the amount of energy necessary to regulate the internal environment.

What Can Roofing Do?

Green roof designs can vary widely from building to building.  However, the LEED certification standards have been designed around allowing buildings to earn credits based on the most critical aspects of efficiency that are related to typical green roofing projects. 

Many green roofing systems will take advantage of vegetative resources as a prime material.  Incorporating plants into the roofing system falls under the “Protecting and Restoring Habitats” regulations.  The plants used must require almost no artificial irrigation, and they may not be dependent on pesticides or unnatural fertilizers of any kind. 

Companies taking this approach to roofing should also cover at least 50% of the surface area in vegetation.  This level of coverage promotes creating a heat island effect, thereby increasing the insulation efficiency of the roof.

If the vegetative roofing does require artificial irrigation, then LEED points can be earned by using drip irrigation whose water is coming from a reclaimed source such as collected runoff from pure sources at use in other parts of the building. 

Energy performance is a large part of the evaluation as well, providing the possibility of earning up to 19 LEED points.  There are minimal energy efficiency levels that must be met before a project can even qualify for LEED certification, to begin with.

  When constructing a green roof, companies must demonstrate a specific percentage of improvement in energy consumption over more traditional methods of roofing the same type of structure.

Additional Roofing Forms 

Not all green roofs must take the vegetative approach.  Many roofs take advantage of recycled materials and waste from other building projects.  This part of the system is organized under the “Material Reuse” and “Recycled Products” guidelines. 

They are meant to reduce the demand for raw materials that must be processed and refined to a great extent before being put into use.  Any materials of this nature incorporated into the design must be categorized as post-consumer or pre-consumer items, referring to their method of production and acquisition.

  These components must, at a minimum, contribute to 10% or 20% of the total value of recycled materials used in the project.  Determining the exact figure for the total value of recycled material is done by weight.  This number is then multiplied by the total cost of assembling the materials into usable components.

Companies or homes installing a green roof can potentially earn close to 30 LEED points.  By merely covering half of the roof with vegetative materials during the construction, projects generally gain two points at a minimum. 

Gaining 9 points from just the roofing system can actually account for 20% of the total points needed for a building to become LEED certified.

6 Reasons Why Solar Power Is The Most Sustainable And Viable Option For Home Electricity Use: Efficiency, Tax Breaks And More 2022

Dependence on fossil fuels has driven humanity to unparalleled stress levels. These fuels affect us in a number of ways that many don’t realize. Gasoline in your car isn’t the only use we derive from drilling into the planet for this resource.

However, for 4.6 billion years, the sun has been blasting away at this planet with a replenishable power source. Let’s look into what makes solar power more superior to other methods.

Renewable

 Solar power will always be supplied by our sun. The day we go without the sun’s influence on our planet, is the day we’ll have bigger problems than power distribution.

Pay-It Forward

Most power companies will pay a homeowner for feeding power back into the grid. What happens when the solar panels are collecting more power than is needed and/or stored. Excess power can be fed back into the power grid and can alleviate brownouts in the area.

Technological Advancements

As advancements in technology increase, so does the understanding and efficiency of solar collectors. Battery longevity, output wattage, and more efficient constructs are constantly being improved upon.

Tax-Breaks

Although the initial cost of installing solar panels on a large scale for the home can reach in the tens of thousands of dollars, tax breaks from the federal government in April can help reduce the overall costs. The savings each month from your electric bill can quite possibly pay for itself sooner than you imagined.

Scalable

Solar panels don’t have to be isolated to operate your entire residence. Smaller systems can be used to offset some of your power costs as in solar-powered water heaters and lighting. You can start off small and keep adding to the array as your budget permits.

DIY Kits

As millions of people look for cleaner energy solutions, hundreds of organizations have put together do-it-yourself kits and will teach you how to build your own solar array. These kits can be of various sizes and can greatly reduce the overall costs of installation.

Solar power will be supplied to this planet long after humankind has ended. It is a power source that needs to be explored more than it has been. What country wouldn’t relish in being the first to provide never-ending power to its people? Visit SolarPower.org and find out more information about how you can wean yourself from fossil fuels.

As the price of oil continues to rise, and as more people than ever wake up to what we are doing to the environment, solar power is rapidly becoming more popular than ever.  In fact, one might even say that a revolution is taking place.  An increasing number of people are finding value in becoming self-sufficient, and solar power is one of the top choices for those who desire to get “off the grid”.   

So just how popular is solar power becoming?  Well, according to a new Rasmussen Reports national telephone survey, 44% of Americans believe that solar power should become a standard method for heating homes in the United States.

Not only that, but according to that same survey, 31% of Americans say that they are at least “somewhat likely” to use solar power in their homes in the next five years, and 13% say that they are very likely to do so.

Those are very encouraging numbers.

The cost of implementing a home solar power system is coming down at a time when more Americans than ever are viewing solar power as a practical alternative.

If you are in need of some inspiration, just check out the following video report about what one couple living in the Herefordshire countryside is doing with solar power…

Of course, solar power is not the only alternative energy source that is good for the environment. There are others who are turning to wind power and geothermal methods of producing renewable energy. But solar is probably the most prominent at this point, and it certainly holds a lot of promise.

If you are looking for a way to help the environment and to become more self-sufficient, we encourage you to check out solar power as a possibility.  We believe that you will be glad that you did.

The Future Of Energy – Top 5 Alternative Sources Of Energy That You Should Know By Now 2022

New sources of energy will be required if our current technology-dependent society is to continue. Fossil fuels have given our society a huge lift as far as energy goes. Few technologies we have created can rival the energy output offered by fossil fuels. However, prices will continue to rise.

Supplies will continue to fall. A few technologies are being developed to take advantage of other sources of energy or improve on current technologies. If they can be developed to their potential, the future will look brighter than ever.

Solar Wind Power

Solar power has always been promising. However, it has always failed to meet expectations. Wind power also has great promise, but it too is seen as too economically challenged to be successful. However, new advancements in both technologies have created new potential for hybrid systems.

These systems would use wind turbines that are covered in flexible solar panels to produce electricity through both sources. As solar panels become more productive and cheaper to make, the possibilities of these hybrid systems become even greater.

In the future, buildings may be constructed to make greater use of the wind and solar energy around them because of these current technologies.

Waste Heat

Around 60% of all the energy used today is wasted as heat. By taking small steps such as taking the heat from a car’s exhaust system and turning that into energy the car uses efficiency could increase by ten percent.

Research is also being done on reducing the waste heat from refrigerators. Taking heat that is currently wasted and using it for productive purposes could help boost efficiency in almost everything we use.

Solar Energy

Solar energy is not just for large-scale energy production. It can be used at the level of individual homes or even individual devices. As solar panels fall in price it will become more feasible for people to install them on or around their homes.

This frees up more electricity on the power grid and helps reduce fossil fuel use. Different companies have also been developing and even selling, solar chargers for cell phones, tablets, and other devices.

Light-Powered Circuitry

Electronic devices operate because of the circuitry within the device. Without it the device becomes worthless. Scientists have recently discovered a way to power circuitry with light. This would eliminate the need for batteries and the electricity needed to charge them.

On the surface, this may seem like boring technology along the lines of solar power. However, imagine having a computer or smartphone that never ran out of power and never needed recharging. Having that kind of energy-producing power in something so small is quite revolutionary.

Water And Carbon Dioxide As Fuel

Current biofuel technology is too costly and too inefficient to replace fossil fuels. However, researchers have discovered that combining genetically altered bacteria with some water, carbon dioxide, and sunlight will produce more fuel per acre than ethanol at a lower cost.

Many people believe that it could be the first step toward replacing the current fossil fuel system with a sustainable alternative.

All of these energy sources hold promise for the future. These options represent only five of the most exciting developments in a fast-moving, highly-dynamic field.

Maybe these options will power the future. Maybe new technologies will be developed that offer humanity more in terms of affordability and productivity. No matter what, now is an exciting time in renewable energy.

Clean Energy To Meet Energy Demand – Do The Right Thing For The Environment Before Depletion

Almost 85% of the energy demands we have is met by non-renewable energy sources like oil, petrol, coal etc. Unfortunately, these resources are limited and with indiscriminate use will deplete and eventually dry up.

Using these fuels also tends to emit carbon into the atmosphere which is toxic and a pollutant. This is the primary cause of the green house effect and global warming.

So what is the solution to this? How do you do the right thing for the environment? The answer to this lies in Clean energy.

Clean Energy

Clean energy is known alternatively as Green energy, Renewable energy or Alternative energy. Basically, clean energy is non-fossil based. Clean energy is considered to be non-polluting, non-toxic, and environmentally friendly.

Generally sources of clean energy are natural sources which are harnessed to produce energy – wind energy, solar power, hydropower, tidal power, geothermal energy and biomass.

Clean energy is increasingly gaining popularity amongst individual consumers as well as businesses and organizations. It’s the best choice for those looking to do their bit for the environment and also increase their nation’s energy independence. In the US nearly one million homes have purchased Green certificates to support this form of energy.

One of the more common sources of clean energy is wind power. For centuries we’ve seen wind energy being harnessed and used by humans in the form of wind mills and sail boats. This source of energy makes use of airflows to run wind turbines. Basically, higher the wind speed more is the power output.

Thus wind power is a very good source of energy in areas with strong winds which are constant, such as offshore and high altitude sites. Wind turbines are being used to pump water, for grinding grains and also to charge batteries. Germany, Denmark, India, Spain and the US account for about 80% of the world’s installed wind energy capacity. Find out if your area too is suitable for utilising wind energy.

Hydro Energy

Water Power, also known as Hydro energy is a very popular and highly effective source of renewable energy. Water has immense potential as an energy source as it about 800 times denser than air. This means that even a slow flow of water or a moderate sea swell has the ability to generate quite a bit of energy.

Hydro power is one of the best, cheapest and cleanest sources of energy. Of course, building dams to harness this energy may prove expensive and pose environmental issues. Energy from water can be harnessed using large-scale hydroelectric dams, micro hydro systems, damless hydro systems deriving energy from rivers and oceans, tidal stream power, wave power, saline gradient power etc.

Solar Energy

A third source of clean energy, and one that is the most freely available is solar energy. With solar energy there is no issue of boundaries of countries and who the resource belongs to. Solar energy is also very important as it is virtually pollution-free and therefore environmental friendly. Solar energy has gained increasing popularity since the 1970’s ever since oil prices started increasing.

In many countries, solar energy is used in daily chores like for drying clothes, vegetables, for pickling etc. Similarly, there are now solar panels available which can be used to absorb sunlight and use the energy for heating and cooking purposes. In fact such is the potential of solar energy that newer factories being set up are using technology to utilise solar energy, helping the environment and reducing their own costs.

Solar energy can be used for cooking, heating, distillation, power generation, cooling, refrigeration, drying etc. For harnessing solar energy products like solar cookers, water heaters, hot air systems, power tower, etc are available. You too can easily setup any of the solar power based equipments in your backyard or on your terrace.

While the initial cost of setup may be on a higher side as compared to the AC powered equipments, in the long run solar power run equipments prove highly economical. Apart from that certain states also offer tax rebates, concessions and soft loans on purchase and installation of such clean energy harnessing products at home or in offices.

Biomass

Biomass is another clean energy source. It is derived from the waste of human and natural activities. The major sources of biomass include by products from agricultural crops, raw materials from the forest, major chunk of household waste etc.

Biomass is very efficient as a renewable fuel as it does not add any additional carbon dioxide to the atmosphere as it absorbs as much when being developed. In countries like India, villages have biogas plants which make use of farm and animal waste to produce gas for home and small industry use. In countries like the US, biomass is being used for heat and power generation.

Seeing how beneficial and economical clean energy sources are, it is definitely the right thing to do for the environment. Take a step towards clean energy today so that our coming generations get to breathe Oxygen and not CO2.
