The search (26) for alternative sources of energy has led in various directions. Many communi- ties are burning garbage (27) and other biological waste products to produce electricity. Converting waste products to gases or oil (28) is also an efficient way to dispose of waste.
Experimental work is being done to derive synthetic fuels (29) from coal, oil, shale and coal tars. However that process (30) has proved to be expensive. Other experiments that are underway to harness power with giant windmills are also (31) being tested.
Some experts expect utility companies to receive hydroelectric power (32) derived from streams and rivers. Fifty years (33) ago hydroelectric power provided one third of the electricity used in the United States, but today it supplies only four percent. The oceans are another potential sources of energy. Scientists are studying ways to convert the energy of ocean currents, tides and waves (34) to electricity. Experiments are also underway to make use (35) of temperature differences in ocean water to produce energy.
Nowadays, some people choose to live and work in the countryside. New ways of working, such as online working, have made it (1) boring for more people to live there. There are both advantages and disadvantages to living in the countryside.
On the one hand, life in the countryside is very peaceful (2). There are less cars and that means that there is less noise, and that it is less polluted(3) . Furthermore, there is more land available in the countryside, and people can often live in bigger houses or flats than in cities. Finally, it is easier to do a lot of (4)Outdoor activities such as walking or cycling if you live in the countryside. On the other hand, life in the countryside can be (5) isolated There are fewer restaurants, cinemas and shops to go to . Moreover, there is little public transport, which makes it difficult to get (6) around if you don't have a car. Finally, you can feel (7) possible if you live a long way from other people.
In (8) conclusion, there are both pros and cons to living in the countryside. However, in my opinion, the peacefulness of the countryside makes it a very attractive option.

Electric cars are better than petrol cars in several ways. The biggest benefit is reduced pollution. In areas where there is a high percentage of electric cars, there is less pollution. But it is important to understand that electric cars still cause pollution. Remember that the electricity to power electric cars has to come from somewhere, which is most likely a power station. Unless these power stations run on solar or wind energy, they are most likely burning fossil fuels to make electricity. The second benefit of electric cars is a reduction in the dependence on foreign oil. There are several countries, including the United States, that don’t want to rely on oil coming from other countries to power their transportation systems. They want the power to come from within their country, and since electric cars can run on electricity from coal or nuclear power stations, there is less of a need to import oil.
