This article explains alternative energy principles and ideas. The fact being that our supply of energy today is declining. Coal and oil are in high demand and are quickly being depleted. Alternative energy solutions are available, although not widely considered. Alternative sources such as solar and wind power could not only provide more than enough energy to replace our dependence on coal and oil, but also benefit the entire planet.
The alternative energies that most money has been invested in so far are solar and wind energy. One of the reasons that these energy sources are so popular is because of the availability of the fuels and the amount of research already conducted into their viability and possible uses. Solar power is probably the most effective and available energy that homeowners can use to help do their bit for the renewable energy cause.
