Well, one invention that we can use NOW is the fluorescent bulb. It may seem more expensive than the classic incandescent bulb, but the fluorescent bulb has a much longer life and it's much less energy consuming than the incandescent bulb, so, within a year (it's life is about 5 years), all costs will be recovered. An incandescent bulb stands for 20 kg of carbon dioxide thrown into the atmosphere.
