Renewable Energy Tips for Your Home

Today, there are many ways to add renewable energy to your home. Adding renewable energy can save you a lot of money on your utility bills every month. You can add solar energy or you can also add wind energy, and if you add both, you will save even more. This savings is not only good for you but it is good for our earth as it will reduce the use of our natural resources to create the power that we need to live.

Many people use a combination of wind and solar power to create their own power. Each has its own advantages, and you should consider them carefully as you start investing in renewable energy options for your home and your life style.

For instance, in many areas of the world, summer is the best time for solar energy creation, but in the winter, wind will produce more power than the sun which is lower in the sky and not above the horizon for as many hours every day. This is why a combination of both solar and wind is the best option. It gives you the advantages of both systems when they work the best. And, of course, solar NEVER generates power during the nighttime hours, but many times, the wind continues to blow. So you will almost always get either one or both creating power for your home.

Where you put your solar and wind renewable energy generators is important.

A windmill is pretty large (the blades can be 10 feet across, and should be 20 feet or so above the ground) so it will need a fair amount of space in which to turn, and a fair amount of wind to keep it turning, so a clear path for the wind will make the system work that much better.
Though they can be placed in racks set in the ground, solar panels that create electricity are usually put on the roof of the home – but, for the most efficient use of the sun, it should be a South facing roof (in the Northern Hemisphere – North facing in the Southern Hemisphere) at an angle to the horizontal equal to your latitude… about 25 – 45 degrees in the continental US. The more space you have available for solar panels, the more power you will generate. You can expect approximately 20 watts of electricity from each square foot of solar collecting cells. So, for example, if you are able to install a 10’ x 20’ solar array (collection of solar panels) you could expect to generate about 4000 watts of power, enough to power 40, 100 watt light bulbs – as long as the sun was shining on your solar array.

(Of course, if you use compact fluorescent or LED light bulbs, you will save much, much more. What is interesting is that replacing your regular incandescent bulbs with energy saving compact fluorescent (CFL) bulbs is one of the quickest ways you can start saving money on your electric bills since they usually consume about ¼ to 1/3 of the power that regular incandescent bulbs do – and LED bulbs consume even less power!)

There are many good books on building your own solar and wind systems to reduce your power consumption from your local power authorities. By all means examine these in depth resources – you’ll be glad you did.

Green Technologies, Solar panels, Wind generators, Renewable energy sources, Solar power

Quoting Wikipedia about Greentech, “Environmental Technology (Envirotech), green technology (Greentech) or clean technology (Cleantech) is the application of one or more of environmental science, green chemistry, environmental monitoring and electronic devices to monitor, model and conserve the natural environment and resources, and to curb the negative impacts of human involvement.” Green technology is the need of the hour. As we came to know you, these technologies are here to curb the negative impacts of the most intelligent species on the planet, homo sapiens, more commonly humans. Sustainable development is the core of green technologies. Inventors and Governments are putting in a reasonable amount of time and money for such a huge propaganda.

Green technologies are a way of harnessing the most out of renewable energy sources. Renewable energy is energy that can be replenished easily. Green technologies are the fastest growing trend today and investors should aim for them as they are profitable as well as a way to give back to mother nature. Not just inventors, but consumers must know that buying green would reduce their energy bill and are also safer than the non-green ones. Previously civilizations started near river banks. They were able to harness water from the river to the maximum and when they couldn’t they adapted. There is nothing permanent except change itself. The way we have treated mother nature with harsh and rude behavior, green technologies can be a suitable compensation. Approximately 20% of electricity produced globally in 2009 came from renewable sources. Out of this, hydro-power accounted for about 16%. In 2012, 9% of the energy consumed in the USA came from renewable sources. This means the USA depends a lot on non-renewable sources. 30% of the energy from renewable sources came from hydropower, while biomass, biofuels and wood, together accounted for about 49%. Green Technologies include usage of various technical knowledge and machinery to give a green edge. One such example is solar power. As we know, the sun is a renewable energy source and the conversion of sunlight into electricity by means of Photovoltaic cells or Concentrated Solar Power is referred as solar power. The International Energy Agency projected in 2014 has gone ahead to state that under its “high renewables” scenario, by 2050, solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively, of the worldwide electricity consumption, and solar would be the world’s largest source of electricity. Most solar installations would be in China and India. Solar panel refers to a panel constructed in order to absorb the sunrays to generate electricity or heating. Solar panels are the cornerstone of solar power and hence the revolutionary green technologies.

Much alike solar power, wind energy is another eminent renewable energy source. Wind can be used for various purposes, including electricity, which is served up by wind generators or wind turbines. A wind turbine is a device that converts kinetic energy of the wind to electric energy. Wind generators are the most widely known green technology machinery and their history dates back to 200 B.C. Wind generators were earlier made of six to twelve sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water, and were used in the gristmilling and sugarcane industries. With time they have developed into magnificent structures built with the expertise and employ a huge sector. A quantitative measure of the wind energy available at any location is called the Wind Power Density (WPD). It is a calculation of the mean annual power available per square meter of swept area of a turbine, and is tabulated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density. Color-coded maps are prepared for a particular area described, for example, as “Mean Annual Power Density at 50 meters”. Indian Wind generator companies like RRB, Suzlon, NEPC are gaining a lot of profit and challenging the European market. On shore and off shore installations of wind generators have increased drastically and are having a leading edge in electricity production as mother nature has been kind to the windmill industry.

When people were still allured by the vast usage of renewable energy sources like solar power and wind energy, inventors like Martin Eberhard and Elon Musk, the founders of Tesla Motors, came up with gadgets that mesmerized the world. Tesla Roadster was first of its kind. A fully electric sports car, designed to meet the requirements of luxury yet reducing the usage of non renewable energy sources was a ground breaker in the field of green technology. Musk, CEO of Solarcity and Tesla, has acquired a solar panel company intending the betterment of human lifestyle. Such a step will prove to be very essential in the path of utilizing renewable energy sources to the maximum. It seems the cost-effectiveness of solar power will also increase due to such investors.

Living the “Green” Dream

With all energy costs soaring almost daily, and the effects of climate change so prevalent, many people are wondering if there is any truth to the concept of “Living Green”. With recent advances in renewable energy technology, it is far easier now than it has ever been to start living the “Green Dream”. These advances have seen big improvements in quality and efficiency as well as cost reductions which have made many products affordable for the average householder.

But first let us define what Green energy is. Green energy is created from natural renewable resources, Sunlight, Wind and Water. Because of this, it is also known as Renewable Energy. It should not be misinterpreted as Alternative Energy, which also includes nuclear power and other carbon use sources.

So are there real benefits on a home or small business level to Green technology? Most certainly!! By installing green energy technology in the home you can save hundreds of pounds each year. Renewable energy technology is gaining in popularity all the time and it is easier to meet your home’s energy needs now, than ever before.

With the information now available about Green Energy, especially on the Internet it is possible to build a wind turbine or solar panel with just basic Do-it-yourself skills. If you can afford a professionally installed system, these are generally more efficient, but savings can still be made, and at a faster rate by building your own green systems.

So how can we utilize green principles in our home or indeed business premises. The process can start as early as the design stage, by implementing passive solar design, and taking advantage of south facing walls for heating and cooling. Installing plenty of highly efficient windows as well as heat retaining bricks, will ensure that you are taking full advantage of passive solar techniques.

The vast majority of us, however, don’t have the luxury of building our own home though. So what measures can the average person take to start living “Green”. As we said earlier Green energy comes from wind, water as well as the sun. If you are lucky enough to have a stream on your property you can harness its hydro electric power capabilities, and any average householder can install a wind turbine to utilize wind power.

Turbines can be installed on rooftops or on open land and and offer total pollution free electricity. Recent improvements in this technology have made turbines lighter and more aerodynamically efficient. They can be purchased from retailers or, for the more experienced do-it-yourselfer, there are a variety of value for money kits available on line so they can implement their own green energy home plans.

However for the majority of us, solar energy would be the most popular source of green energy due to its multiple use options. There are actually 2 types of solar energy: Thermal as well as Light. Homeowners can install a thermal rooftop solar hot water collector for all their heating needs, as well as installing solar panels, which use photovoltaic cells to generate electricity. Again, advances in solar technology have reduced these from giant panels to thin film layers, which are much more efficient and require less sunlight. Both of these systems can again be expensive if bought retail and installed professionally, but again there are an increasing number of reputable on line sites where you can build your own panels at a fraction of the retail cost.

Ideally a green energy home would combine all 3 sources, to generate electricity. Considerable savings can be made, grants may be available for installation costs and even possible profits from selling back your excess electricity generated. By using wind, water and solar energy you are truly going Green as they have no negative effect on the environment.

Green energy technology certainly does work and can be utilized by homes and businesses alike. Renewable energy can save you money, and with increasing consumer use, it will minimize the effects of global warming and our reliance on fossil fuels. So don’t delay. TAKE ACTION NOW and start living the “Green Dream”.
