Alternative, Green, or Renewable Energy Technologies

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 plants have been developed in in many nations. They are now more strategically placed in order to improve the national electricity grid. 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 progressive countries across the globe are also running pilot facilities.

Hydroelectric power has been with us for a while. At current hydro dams, 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, trapped in layers of rock, through the earth’s 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. Most commonly, the retail stockpiles of bio-diesel have been created using rapeseed 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 generated electricity. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. This involves the manufacturing of solar panels which gather and focus the sun’s energy, and translate it into electricity. In some, hot water can be generated from the sun via a solar water heater. As with wind energy, solar energy creates absolutely zero pollution.
