Alternative Energy

The term alternative energy is generally used when describing a source of energy that does not rely on fossil fuels. Labeling energy sources that are non-fossil fuels as alternative has in recent years become less favorable for some sources. As an energy source becomes increasingly mainstream, the supporters of that source tend to focus less on the fact that it is an alternative and more on the fact that is a valid source for energy supply.

Different types of alternative energy include green and renewable energy like:

- Biofuel Energy
- Geothermal Energy
- Hydropower
- Solar Power
- Wind Energy
