There is an increasing demand for energy across the globe, of which there are natural resources waiting for us to harness if for our use. We need to spend more time and money into research and seeking ways to make good use of this alternative energy, rather than using the old fossil fuels and creating more damage to the environment.
Wind power is an alternative energy resource that we harness with wind turbines. They are continually being developed with demand and are progressively becoming cheaper and more efficient in energy. There are many “wind farms” which can be seen, that are strategically placed so as not to jeopardise the bird population in their natural environment. The first wind turbines were not so well placed.
The most famous of all alternative energy resources is solar energy, which the majority of people are familiar with. There are lots of products on the market which use solar power, that people buy for home use: solar lighting, solar lanterns and fountains for the garden are a new innovation, etc. Solar cells are manufactured which collects the sun’s energy and focuses, so that it can be converted into electricity to light buildings and for heating, like hot water. Solar energy is like wind power in that there is zero pollution created, which is a positive for the environment.
Governments and investors see Ocean Wave Energy as having great potential for generating energy. In France, a generator of this kind has been operation for several years, deemed to be a great success. In Ireland and Scotland there are now facilities up and running in their experimental phase.
Hydroelectric power plants have been around for years and the powerful generators that have been set up, have proven to be much cleaner and better than power grids at producing electricity. There are, however, limitations as to where you can place one as you have to build a huge dam in a suitable location for the water. For this reason, there are new much smaller localised hydroelectric generators that have been set up recently in rivers, so that they can be localised to accommodate them.
Geothermal energy lies just under our feet directly and there is an abundance of it available. A few miles just below the surface of the earth, we can tap into this energy. The hot molten core of the earth heats the water on the surface, to produce energy, which is harnessed once it turns into steam. This steam is used to drive turbine engines so as to generate electricity. More research should be done on geothermal energy so we can tap into its resources and develop it more for use.
The waste that we produced is often disposed in landfill sites, which decomposes over time and so gives off methane. By using it before it gives off too methane which is damaging, we can create energy from it. It is mainly used as gas for fuel cells for use in standard gasoline generators.
Ethanol is a biofuel used as a substitute for gasoline. This alternative fuel is easy to make and process using such products as corn, grapes, sugar cane, wheat, wood cellulose and wood chips. It is still debatable as to whether it is economical as lots of arable land is required to grow the crops, and also concerns of the pollutants from use of this product. It is localised in some areas and technologies are still being refined for extraction and admixturing.
There is a lot of investment by entrepreneurs into Biodiesel energy which is created by many different plant oils such as palms, rapeseed, soybeans and sunflower oils. It is now competing with fossil fuels and many companies have shown a commercial interest as it is cleaner burning than oil based diesel and is environmentally friendly.
Atomic energy is being created by regenerating nuclear plants for a carbon free energy source with nuclear fission. A great amount of power can be generated which makes this type of energy very efficient. The concern from people is of the radioactive waste product of atomic energy, although there is very little it still takes hundreds of years to decay before it becomes harmless.
