We can develop alternative sources of energy, and unless we try we’ll never succeed. Instead of using fossil fuels we should be concentrating on more economical uses of electricity, because electricity be produced from any sources of energy. If we didn’t waste so much energy, our resources would last forever. We can save more energy by conservation than we can produce for the same money. Unless we do search on solar energy, wind power, tidal power, hydroelectric plants … our fossil fuels will run out and we’ll freeze or starve from the sun, the waves, and the winds last forever. We won’t really survive unless we aren’t working on cleaner and safer sources of energy.
