Poland reveals its new super car. [56]
What do you mean? To get 4 kwh by heat pump, 1 kwh is spent? So, 3 kwh is a plus. Are you saying heat pump is useless due to its low efficiency in general or in some circumferences? It is known sure. But, efficiency calculation, in other better words, philosophy behind the efficiency is not so correct. When something is free everywhere, efficiency of it doesn't become important anymore. In the case of petrol, for ex, which is not available everywhere, efficiency becomes important due to its limited amount of petrol.
Another thing, another problem is the energy needed, energy needed to drive the system in the world today which is like a super balloon unnecessarily is of course big, and, a big portion of energy being used today is wasted for unnecessary items such as warplanes, big engine cars, etc etc. Natural energy sources will be enough to drive a natural life. Heat pump, photovoltaics, wind energy technologies, etc etc will be enough to provide a natural life. When such energies are used more often, petrolium will be less important for energy need as petrolium will be used more for items such as plastics, etc. If we are focused on petrolium, gas, etc more, I know those resource owners will be happy as world will be dependent on them, but, then, there will be wars more and more for such energy sources concentrated on some regions. When people stay away from such energy sources like petrol, etc those people who captured such energy sources like oil, gas, etc can find themselves in marsh. Then, those oil, gas, etc lords will try to save themselves out of marsh and will try to share those resources too with the rest of the world and this will make the world a globalized social world..
For sure... ;) In germany, companies that have wind generator farms complain that solar energy producers consume 40% of total state subsidies amount producing only 10% of "green" electricity. ;).
40% of state subsidies consumption for 10% of green electricity?
What do you mean here? You mean money is spent much for little energy?
It is due to the material costs and high material costs are due to unnecessary use/waste everywhere in the world. World is not being drived by knowledgable people, but, by priests, imams, monarchies etc even in technology fields. Then, such illogical things happen even in technologies. Where there is no, for ex, petrol, that little energy by wind is very important and its price must be as gold price, under these non-global asocial world, if you understand what I mean.
