Everything Wind Power & Wind Mills

There is an ever increasing demand of sources of energy, in particular oil, coal and gas fuels.The oil supply has recently climbed up to unprecedented levels and its prices increased. 

This is coupled with the fouling of the earth’s atmosphere with the continuous evolution of carbon dioxide, nitric oxide and other noxious gases, which inevitably lead to global warming and catastrophic climate change.

Coal is said to have a comeback, more so in Asia domain as China. Though this might not solve the problem of evolution of CO2, the main source of global warming. There have been some attempts to have power plants using what is so called “clean coal”, i.e. release less carbon dioxide in the atmosphere, but that won’t be available for years to come. The problem is also tackled in another way by attempts to sequester CO2 in deep crevices in the earth crust between impervious rock deposits. But again this may gain fruit in few years to come.

Hence the feverish and serious seek for other alternatives as a source of clean energy bio-fuels, solar and wind drives.

The main alternative to coal and oil sources is to use bio-fuels from crops such as bio-ethanol. This provoked a boom in planting; but the burning of the bio-fuel may not even decrease the greenhouse gas emissions; the fuel production at the expense of food could worsen hunger worldwide. Farmers in the US have planted maize and corn in magnanimous quantities, as a derive to increase bio-ethanol production, which inherently have increased its prices as human and animal  food  source.  

 The South American countries, particularly Cuba use bio-ethanol produced from sugar cane as a mobile energy source, though this did not solve the problem of the feeding urban population, nor did it decease  the price of food commodities.

A recent attempt implemented in Papua New Guinea as the use of coca nut oil squeezed off from the kernels of the fruit, was used as a bio-fuel instead of diesel oil for tractors and other heavy vehicles. It was of a slow burn however, and cannot initiate proper drag, unless blended with diesel.

The world demand for food has been spiraling, partly because of the increase in world’s population and industrialization in making more of those people prosperous enough to eat better, and more, which takes a lot of grain and cereals to produce. The irony here is that the increase in the agricultural research and development produced unprecedented crop yields in the late 20th century, counterbalanced with the big population growth, whence hunger prevailed and will continue to bite.
