Solar energy has long been an effective way for humans to accomplish tasks that they could not perform previously. The earliest humans quickly learned that their meat would taste much better when it was cooked naturally underneath the warm rays of the sun. Mankind also found out that a bath taken in water that was warmed by the sun was much more satisfying than a bath taken in chilly waters. Energy that is emitted from the sun is all around us and can be harnessed in order to ease the burden that is placed upon the earth’s natural resources.
Solar energy is not a complete alternative to fossil fuels and carbon forms of energy, but it is an excellent way to give mankind a variety of means to receive energy to fuel our cars, heat our homes, and cook our food. The use of solar energy has grown at a rate of about 30% annually for the past 15 years, compared to a demand growth in carbon energy of about 2% per year. Solar energy is becoming much more feasible and efficient than it used to be. Technology barriers have long halted the progress of solar energy, but many of those barriers have been broken in recent years. The cost of manufacturing a photovoltaic cell has declined on average by 4% since 1995. Newer and more effective technology has allowed these prices to decrease and make solar energy affordable. As of right now, the government has approved for solar energy subsidies to be provided to those who harness and use this form of energy. Most engineers believe that solar energy prices will continue to decline. click here to learn more about the microphone
Another advantage to solar energy is that it can be considered an infinite source, as far as mankind is concerned. It is true that the sun will eventually lose its deuterium and tritium fuels and burn out, but that is not projected to happen for a few million more years. At that point we will have bigger problems on our hands. Every square foot on our green earth is the beneficiary of solar energy nearly every day. This energy can be harnessed through the use of photovoltaic cells and solar panels that convert the solar heat into usable energy. Again, the rays from the sun are not the ultimate answer to our energy needs but solar energy is a great way to ease to burden that our fossil fuels carry.
