James Post asked WIND ENERGYBigger windmills mean lower cost per kWh Therefore the mainstream of the market is – MW Mega Watt – kW peak capacity windmills Their average yield is up to MW depending on wind conditions However big systems also bring big problems with them complexity of installation accessibility maintenance But moreover they require a very strong net mains Currently even strong nets can not handle more than – participation of the big systems The worst case scenario must be considered maximum wind output at lowest power requirement at any time In the western world due to industrialization the difference between minimum use and average use is not that big but it reduces the wind anyway As the average and maximum yield differ substantially this further reduces the wind The big systems have costly options to waste energy into dummy loads in extreme cases but practically the maximum wind is around of the average power use In Western hemispheres this is currently also seen as a practical limit because of the limitations to place wind mills on land people do not like the view Ten percent as useful as it is is not even covering the growth of

does geothermal produce greenhouse effects

Dane Bergen asked Geothermal Renewable Energy is a harmless one that is made from the heat of the earth It does not produce any greenhouse gases Underground water near volcanoes gets heated and even boiled at high temperatures and produce steam These are found at a depth of m the water is collected by drilling wells The steam and hot water is separated Steam is purified and used in power plants to generate energy Water is used in reservoirs to produce more steam This is an outline that explains generation of geothermal energy Establishment of a geothermal plant has to face many challenges as it requires an appropriate location Drilling wells to get the water may affect nearby areas also So it is very important to select location without affecting natural habitat This provides many environmental advantages as it is pollution free clean and renewable This is referred as a renewable energy as it is obtained from an unlimited resource natural heat of the earth The main advantage is that it reduces the usage of imported fuels for power generation Chevron is the first company to manufacture geothermal energy industrially and now they are the largest producers in the world
