What is renewable energy?

Renewable energy sources are those sources which are inexhaustible. For example, solar energy and wind energy are constant energy supplies. On the other hand, fossil fuels like oil, coal or natural gas are exhaustible sources with limited supplies.

Solar energy is a prominent source of energy when it comes to heating, lighting houses or even for generating electricity. This electricity can be used to drive today's cars. Though this technology is in its first stage of development, rapid developments in this field have promised a pollution-free environment thanks to solar powered cars in the future.

Hybrid cars use less fossil fuel. This helps in reduction in the consumption of renewable energy resource. It also reduces the emission of green house gases into the atmosphere. Hybrid cars that use biodiesel as a fuel are also available in the market. These hybrid cars provide energy conservation and save a lot of money. They are fuel efficient cars and have the capacity to stock up energy and use it again with the help of battery used in it.

Renewable energy source is becoming an important energy resource that can be utilized as a cost effective substitute and can save the world from energy crisis.
