When oil was first discovered, it seemed the answer to everyone’s problems. Electricity, fuel for cars, rubber, plastic and heating fuel were all made from the crude that came straight out of the ground! But there is a huge cost to pay when you take and never give back as most people are now finding out. It took millions of years for the earth to produce fossil fuels and it will take millions more to replace. Since this is impossible, replacing petroleum seems the only option.
Solar energy for homes has progressed, as has wind power in certain areas of the country but not fast enough. To make matters worse, the United States is not the only nation to whittle away at the oil reserves. China was once a net oil exporter in the 1990s but has now become the world’s third-largest importer of oil. Second only to the United States, China has increased their need for oil, cutting into the supply even deeper. Third world countries are also quickly catching up and our time is running out.
In addition to solar energy for homes, other methods of natural alternative energies have been studied and put into place in trying to create a more sustainable planet without the use of petroleum. Geothermal energy uses the heat from the earth to produce steam that in turn powers electric generators or turbines. One problem with this type of energy, however, is you never know when the steam will suddenly cease.
Hydroelectric energy is another option that changes water into either kinetic energy or tidal power. Pressure and flow of the water creates no waste or pollution and can be large enough to service communities. The downside is that dams are very expensive to build, not everyone lives by a flowing body of water and the stream of water has to be steady.
Wind power has made great strides. Wind power works by means of huge turbines harnessing the wind and converting the energy from the turning turbines into electrical current. The electricity can then be directed to a home where power can be stored and used when needed. Not everyone has enough land to use this type of renewable energy or have the consistent wind needed for continuous power generation. Large wind farms in ideal locations can power entire towns but the cost of installing these units is immense.
Photovoltaic solar energy uses the power of the sun to create energy. There are several methods for using solar energy for homes without much work. Outdoor lighting is a good example of solar power that gathers the sun’s rays and emits the energized light at night. The same type of principal can be used to capture the sun, store and convert into electricity around the clock in your home. If you buy solar cells you can accomplish this by putting together solar panels and installing them on you roof. Solar air conditioning, solar water heaters or a full solar energy for homes system is possible and one of the most positive of all alternative energy methods.
Building solar power for your own home is possible, given the right tools. Visit earth4energy.com and learn how to build solar panels. A structured alternative energy system is not only for engineers and businesses but can be completed and placed by homeowners willing to learn the basics.
