Green Technologies - innovation and climate change – sustainagility

Scientists can examine ice, but they cannot tell out anything about our future. Even if scientist has lived thousand years he won’t be able to do it. The graph in video shows that the amount on carbon dioxide rises and then rises the temperature, but it is not so, it is exactly the opposite. One way to save energy is to build better buildings, because big headquarters are built to last only for 30-35 years. Building them up and pulling them down needs a lot of energy and about 30% of building energy is spent on it.

It is thought that if in Tokyo 50% of all roofs are green it will save 1 million dollars a day of Tokyo businesses in cooling costs. Street light use 5% of energy, but it can be reduced to 2%. Usual TVs should be replaced with Plasma TV, because it saves energy more. By driving electic-car, it is possible to save energy about 20% and reduce global emissions . Carbon dioxide is used to grow tomatoes. Tomatoes which are eaten, have come out straight of exhaust of engine and gas turbine burning gas. But still this carbon dioxide finds its way to atmosphere through our bodies. It is possible to save energy if you isolate your freezers what freezes fish. Then you can reduce your freexing temperature. Deserts would be amazing places to storage sunlight energy. But to do this, we have to forget AC, because we need DC lines. If many big countries would say, that roofs have to have solar cells, it saves a lot of energy and saves also money . In future, all new power stations have to offer carbon dioxide capture and also must pump it away.
