Wind Energy is a cure worse than the disease. PV (Photovoltaic Solar panels) is one of the two most benign major power generation technologies. PV installed on roof or parking lots imparts almost 0 additional environmental cost. PV is also taking the Suns energy directly and converts solar radiation it into electricity. The conversion losses are very low! PV can be installed anywhere, works in any climate and is very robust. It is also exceedingly cheap and lasts (go with name brands) a very long time (30+ years) with little maintenance. Whereas wind uses that same solar radiation converted in heated air, converted in moving air, converted in rotating mechanical energy, converted in electrical energy ( this later part at a max efficiency of about 50% ). Wind energy has consequently very poor efficiency overall. But the worst is its huge footprint; the largest windturbines block more air (greater surface area) than the empire state building. Their foundations are ma
Definition of Sustainable development is utilizing resources at present without damaging on them for future generation. The tourism which specially promotes this statement known as sustainable tourism. Sustainable tourism included several tourism sectors such as Ecotourism etc. First most characteristic, the sustainable tourism is a nature based tourism. Therefore it has a natural destination not like other mass tourism etc. It promotes natural awareness and respect. it tries to mitigate environmental damages and minimize impacts, such as exceeding carrying capacity etc. This tourism supportes the improvement of social, economic and environmental development equally. Therefore all three parties are given benifits. Sustainable tourism also provides positive experiences for both vistors and hosts. And also people around the host known as local community. It is important. Visitors are to be taught early about the place to be visited, and when even entering to the place they are al
