What is the main source of energy at present?
what are some alternative sources of energy?
what are their advantages and disadvantages?
The main source of energy at present is fossil fuel.
Some alternative sources of energy are wave energy, solar energy, biofuels, natural gas, geothermal power, wind energy, biomass energy, tidal energy, hydrogen gas, etc.
Their advantages are that they are renewable and is most likely to never run out. Also, they are easier to find than fossil fuels. They produce little or no waste that is harmful to the environment like carbon dioxide or methane so they are more environmentally friendly. Their disadvantages are that they don't produce as much energy/electricity as fossil fuels. Another disadvantage is that they rely on their surrounding. For example, wind energy needs to be generated at a windy location and needs wind turbines that take up a lot of space or solar energy needs to be generated at a sunny area and needs lots of solar panels.

Read the passage, then answer the questions below (2.5pts)
Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the Sun.
At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total population.
Many countries are already using solar energy. Solar panels are placed on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy, too.
Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar power instead of gas by the year 2015.

We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuels. The amount of fossil fuels in the world is limited. Therefore, we must save it, and at the same time we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, the wave, and the water. These sources are not only unlimited and available but also clean and safe to the environment. Peop...
