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 .

Solar energy is a long lasting source of energy, and it can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on the roofs, so we do not need any new space. Compared to other renewable sources, they also possess many advantages : wind and water power rely on turbines which are noisy, expensive and which take up large space. Solar cells are totally silent and non – polluting. As they have no moving parts, they require little maintenance and have a long lifetime.
What is the passage mainly about ?
 A. solar energy B. the advantages of solar cells
 C. the disadvantages of solar cells D. Renewable energies
2. Why don’t we need new space in order to use solar energy ?
 A. Because solar energy can be used anywhere.
