Alternative energy refers to sources intended to replace fossil fuels without their negative consequences like environmental damage. Renewable sources are seen as alternatives to harmful fossil fuels which are rapidly depleted and cause pollution affecting the ozone layer and climate. Various renewable concepts in development include algae that provide electricity, solar and wind power, generators that use wind and water or the Earth's rotation, and cars powered by fuel from CO2 which could provide a cleaner, healthier future with more stable prices and national security.
