Solar electric system generates power from the sunlight. Photovoltaic abbreviated as PV directly converts sunlight into electricity. It utilizes sunlight with no moving parts; hence operating costs are very low and environment friendly. Its feature of modularity allows developing a solar system as per need of utility consumers.

The use of atomic energy is an alternate source of energy has vast potential. Normally nuclear reactor runs fantastic rate of 80% efficiency. Like all other sources of energy, there are residue materials for nuclear reactors too. The disposal of residue is the core area of concern for preservationists. It emits radioactive rays for very long period and therefore proper disposal is necessary. 50% of the power requirements of 5 states of United States are met using nuclear reactors.

Biofuels can be used as an alternative energy source. These are cost effective as well as environment friendly. Biofuels are generally derived from the ethanol. In future the energy sources to be derived from ethanol will increase. The demand of diesel and gas will also reduce in future. Globally, Brazil is the number producer of biofuels followed by United States.

We can’t deny the importance and advantages of biofuels over the traditional petroleum based fuels. Energy crises has accelerated the demand of the energy alternatives. Anyhow, a boost in the biofuel industry is expected in the following years.

This solar system compensates the usage of energy by consuming the solar energy. Such devices are the outstanding alternates for energy. Their usage must be appreciated. The most important thing is aware the people about its uses.

It was said by President Obama at the United Nations conference on climate change today that “there is no time to waste” in the battle against the warming of the planet.

On Monday, The White House announced that it will be initiating a new program, spending $350 million over a period of five years in order to supply developing nations with clean energy technology to combat greenhouse gas emissions and reduce global warming. The funding will be granted by drawing funds from international partners.

A legislation was passed last week by the New York state to provide loans for households and businesses that wish to improve their energy efficiency.
