Even though renewable energy sources can be expensive to install initially they can provide cheap and clean energy for many years. This makes them financially affordable in the long run. Solar power, once thought only to be advantageous in the warmest of climates is now proving to be viable almost everywhere. The same has happened to opportunities for wind power. We can now effectively take advantage of any force in nature that can generate power, store that power in batteries and supplement our energy needs. Even the chemical forces in nature allow us to create our own fuel from plant byproducts. The future is very bright for renewable energy sources in our homes.
