The benefits of renewable energy are considered from two perspectives - price and abundance. While most equipment or vehicles run on renewable energy, it costs much more to run on renewable energy. For example, these vehicles or equipment run on low cost of ordinary gas or oil. On the other hand, renewable energy sources such as solar powered vehicles are difficult and expensive to operate in any corner. Non-renewable fuels are cheap , they have more energy than a small amount , just as much electricity is available from a small amount of uranium.
