UK currently has around 186 (2008) wind farms with 7 large off shore farms and a few other farms under construction.Bio-ethanol (type of bio fuel) - is an alcoholmade by fermenting the sugar components ofplant materials and it is made mostly fromsugar and starch corps.

However, if man can evolve to The investigation and development of moreuse renewable fuels which don’t cause ecologically sustainable fuels, as well as aclimate change, all will be OK. more responsible consumption by companies and consumers, can have a highly positive effect on the environment. On the one hand, the concept of corporate social responsibility (CSR) indicates the commitment and the duties of private companies of integrating in its activities the social, economic and ecological concerns of civil society. Thus, the development and use of biological fuels contribute to a large extent to reducing the negative ecological impact of its activities. On the other hand, citizens and consumers also have a responsibility towards the environment, which they can exercise by acquiring products that have a lower polluting impact. Also, they can carry out what are called "eco-gestures" which are simple and 7

Particularly,the promotion and development of lesspolluting energies are being encouraged, aswell as the production of moreenvironmentally friendly fuels.One of those bio-fuels is bio-ethanol, which isbut ethanol of agricultural origin or ethylalcohol, the same as can be found inalcoholic beverages. Bio-ethanol comes fromthe transformation of vegetables containingsucrose, such as sugar cane or beetroot, andis obtained from the fermentation of the sugarextracted from the sugar plant, or by theenzymatic hydrolysis of the starch present incereals like corn or wheat.
