Around the world many energy sources such as fossil fuel and coal are being depleted.
In the current situation, scientists and others are working to develop new, alternative sources of energy.
These alternative energy sources work to provide energy to homes, vehicles, etc. without the negative environmental impact of fossil fuels.
Examples of alternative energy include wind power, solar energy, and hydro power.
The process of providing these alternative sources of energy is one of the current, leading topics in environmental studies.
