IG Phy – Energy Sources

Fossil fuels such as coal, oil, and natural gas are renewable energy sources.

The process of burning fossil fuels releases sulfur dioxide and carbon dioxide.

Biofuels are made from non-renewable resources.

Biofuels can be produced using microorganisms.

Wind power is a non-renewable energy resource.

The main disadvantage of wind power is that it can only be harnessed when the wind is blowing.

Dams store gravitational potential energy which can be converted to electrical energy.

Water power from tidal systems is a non-renewable energy resource.

Solar cells convert light energy directly into thermal energy.

The main disadvantage of solar energy is that it cannot be produced at night.

Geothermal energy is obtained from the thermal energy within the Earth.

Nuclear power plants produce energy through the process of fusion.

Nuclear fuel produces more energy per unit mass than fossil fuels.

The energy from the Sun is responsible for creating wind and waves on Earth.

Fusion reactions, like those in the Sun, are currently used to produce electrical energy on Earth.
