Alternative energy is usually the name of energy from a source other than the original fossil fuels like gas, coal and oil. Alternative energy is often the background noise, but unfortunately not a popular use is still the most important ' use of renewable energy. Alternative energy sources can be wind, solar, biomass and energy of the Gulf stream.

Another factor that has caused the population problem. People are using wood, minerals, freshwater, food and energy every day. The increase in energy consumption and pollution is increasing, with a great influence on the degradation of conventional energy sources.

We are currently heavily dependent on non-fossil fuels and other nonrenewable energy sources. It causes serious damage to our environment today, and if positive steps are not taken to reduce the consumption of it will have a huge impact on future generations. The majority of the population depends on currenton non-renewable energy.

When we burn fossil fuels that produce carbon dioxide (CO2). When the carbon dioxide in the atmosphere, falls the sun's heat and prevents heat from escaping Earth's atmosphere into space. Carbon dioxide is a greenhouse gas, the CO2 is increasing in Earth's atmosphere, which led to a general increase in temperature on Earth, which we call global warming.

Renewable and alternative energiesThis is a must. Renewable energy has been obtained from sources which can regenerate after consumption, and for these reasons, unlike fossil fuels to renewable energy because of less greenhouse gases.

Some countries offer tax breaks and subsidies to the private sector to encourage companies to respect the environment. Currently 14 percent of world energy is renewable energy, but the potential for AER (Alternative Energy resources) may be sufficiently broad to cover this many times.

Several sources of AER is solar, wind, rivers, rain and geothermal heat. Wind energy is derived from windmills turning, there is a major polluting source of energy with low costs per year, although the initial cost to create it are high. Solar energy comes from the sun. The rays of the sun can be collected and converted into heat and electricity, you can even heat or heat is converted> Energy (which can be used to heat the water, but can also be used to heat homes and build and even greenhouses.

Biomass energy comes from wood, manure, vegetable waste and many others. Biomass has many advantages and benefits, the main one is that the material is released or be dumped. Fuels such as ethanol from biomass and can easily be used as an alternative to gasoline.

Hydro, water, electricity or hydraulic power is energy,crops, the movement of water.
There are different forms of water power in use or development. Some are purely mechanical, but in a very specific way to generate electricity. Major categories include:

* Water is life, this has been used for hundreds of years to drive mills and machinery
* Hydro, usually with regard to hydroelectricity, or run-of-the-river settings
* Hydroelectric Damless, this recording is the kinetic energy of rivers, streams and oceans
* Vortexforce that creates vortices that will be used for energy
* The energy of the tides, which absorbs energy from the tides in horizontal direction
* The flow of the tides, is not the same, but vertical
* Wave that uses wave energy
* Marine current power to capture the kinetic energy from ocean currents.

This only shows that to reduce the negative impact we have on earth, we simply choose alternative methods toenergy. If we do that we have a bright and healthy future for our planet to see for our children and our children's children.
