We can develop alternative sources of energy, and unless we try we'll never succeed. Instead of
burning fossil fuels we should be concentrating on more economic uses of electricity, because electricity
can be produced from any sources of energy.
If we didn't waste so much energy, our resources would last longer. We can save more energy by
conservation than we can produce for the same money. Unless we do research on solar energy, wind
power, tidal power, hydroelectric plants... our fossil fuels will run out and we'll all freeze or starve to
death.
As they have no moving parts, they require little maintenance
Many countries are spending much more time and money on research because the energy from the
sun, the waves and the winds last forever. We really won't survive unless we start working on cleaner and
safer sources of energy.
