Education of the masses with regards to alternative electricity sources is the primary goal of advocates keen for renewable energy to be used more throughout the world. Most energy that is used today in our homes and cars come from fossil fuels like coal and petroleum, with estimates suggesting around 75%. Estimates suggest that nuclear power accounts for about 20% of electricity and the rest is created from renewable energy sources. It is possible to produce electricity from biomass, geothermal power, wind power and solar energy and this type of electrical production is much kinder to the environment.

Electricity production is maintained and created by the movement of a magnet around a conductor. This can be achieved by having two conductors in salt water, shining a light on the conductors or by touching the conductors together. The energy produced to keep the electricity moving comes from absorbing energy or energy collected for burning fuels. This energy is needed to keep the copper wire found between two magnets spinning as this is the most common form of electricity generation and delivery.
Wind power is one of the best forms of renewable energy but one of the least utilized. This is unfortunate as much of the electricity needed by the United States could be supplied by wind power, but knowledge of it's effectiveness if growing. Wind power is the most environmentally friendly electricity sources and is the most efficient of any electricity production as it produces more electricity then for a small amount of wind power.
Solar power is about converting solar light into electricity. This is a well-known electricity source that has been made many advances in recent years. Home solar units and commercial solar energy are becoming much more popular with any excess collected energy being fed back into the electricity grid.
Converting your home to solar energy is an option that many homeowners will take up in the near future and after the initial costs it will make a significant dent in your home energy bills for a long time to come. The initial installation costs can be rather high, but there are numerous tax and other incentives available to lessen the sticker shock.
Hydropower generates electricity from the kinetic energy stored in moving water, so whenever you venture past a dam you will also notice an electricity generator or station nearby. Falling water that passes through a turbine created mechanical energy that can be transformed to electricity. The classic instance of this ocurring was in Niagara Falls when a mouse caused a large black out by chewing through a wire. There exist small hydro electric generators that can be used to generate electricity if you have a significant supply of running water on your property.
Biodiesel can replace petroleum in many vehicles and is used by many trucks and tankers that make long haul journeys. Biodiesel is produced from animal fats and vegetable oils and was first used in 1895. Pretty much all vehicles can be converted to running on biodiesel, although there are some unusual consequences at times, like your car smelling of French fries if you use straight vegetable oil!
