We can get away from the fossil fuels by leveraging alternative energy sources more effectively. The dirty coal energy plants can be decommissioned by turning to alternatives to these energy sources. Most of our energy can harness if we only try to research and develop the renewable energies needed to do so.

One of these renewable energy resources is solar energy. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. "Solar energy farms" have been springing up in many nations, and they have started to be more strategically placed. Over time, they are not causing environmental issues as previous placement of solar panels may have caused.

The following sections provide a summary overview of many other renewable energy sources being researched, developed, and deployed throughout the world.

Ocean current energy is discussed by governments and investors as having untapped energy generating potential. A ocean electricity generator in Europe has been in operation for a long time. It is thought to be a great accomplishment. The Irish and Scots are also running pilot facilities.

Hydroelectric power has been with us for a while. Where it is set up, it is a clean generator of electricity. Because water and gravity is used, it is more effecient than a grid powered by natural gas. There are restrictions to the availability of the right places to set up a large dam. Many river based, or small and localized, hydro generators where created in recently due to this limitation.

Geothermal energy is extremely abundant. Since it lies directly beneath us, we only need drill just a few miles below the earth's surface to find huge amounts of energy. This energy is produced by the heating of water, located within the Earth, through the actions of earth's fantastically hot molten core. The water turns to steam, which can be harnessed and used to drive turbine engines which in turn generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Biodiesel energy is created out of the oils contained in plants. So far, the commercial stores of biodiesel have been created using soybean and sunflower oils. At the time of this writing, biodiesel is typically produced by agricultural corporations or those who want to experiment with renewable energy. Venture interest from companies across the World is on the rise. It burns much better than fossil fuel diesel.

Another renewable energy resource is solar power. It is the one that becoming more cost effective every day. This involves the manufacturing of solar panels which gather and focus the sun's energy, and translate it into electricity. In other cases, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.
