Read the passage below and an answer the question .we can develop alternative sources of energy,and unless 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 source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation 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 starve to dealth . 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 safer scour of energy . 1 can electricity be produced from any sources of energy?2 what would happen if we didn't waste so much energy?3 why are many countries spending much more time and money doing research on energy from the sun the waves and the wind?4 what will happen unless we start working on cleanr and safer sources of energy

Our non-renewable energy sources such as coal, oil, and natural gas will (1) __________ out in the future. That's the (2) __________ why we are looking for alternative sources of (3) __________ which are cheap, clean and effective. These (4) __________ of energy will not cause (5) __________ or waste natural resources. (6) __________ power is one of them. It's currently the cheapest source of large-scale renewable energy.

Most wind energy is produced from turbines that have three 60-meter-long blades. The wind spins the blades, which turn a shaft connected to a generator that produces (7) __________. Now, mass production and technology advances are (8) __________ turbines cheaper. In 2000, cumulative wind capacity (9) __________the world was 17,000 megawatts. Fifteen years later, this number increased sharply to 430,000 megawatts. It is predicted that with this pace of growth, (10) in 2050 one third of the world's electricity needs will be fulfilled by wind power.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.
