10. Read Text 3B and try to identify what source of energy each paragraph describes using the words below. wave energy, nuclear power, solar power, fossil fuels, wind power, geothermal energy, tidal energy, hydropower,biomass energy, hydrogen energy Text 3B What Are Different Sources of Energy? There are 10 main different sources of energy that are used in the world to generate power. While there are other sources being discovered all the time, none of them has reached the stage where it can be used to provide the power to help modern life go. (1) __ systems can harvest the energy of the sun through using collector panels which can then be used for the production of electricity. It has grown in popularity since the oil crisis and more and more countries rely on this energy for various purposes. (2) __ is the energy we capture^2 from the movement of air and convert into electricity. Today it is booming more than ever. Recent innovations that allow wind farms to appear are making them a more common sight (3) __ is heat that is generated within beneath^3 the Earth. High temperatures are produced continuously inside the Earth's crust'by the slow decay^5 of radioactive particles . This energy is a clean renewable source that can be harnessed for use as heat and electricity. (4) __ involves the use of hydrogen and/or hydrogen-containing compounds' to generate energy to be supplied with high energy efficiency, numerous environmental and social benefits. as well as economic competitiv eness". According to the lates research, hydrogen . which has been regarded as a potential clean energy solution for decades , may finally be ready for the spotlight? (5) __ is a form of renewable energy which is created by converting energy from the regular rising and falling of the level of the sea due to alternating sea levels into electricity using various methods. The generation of energy through this power is mostly prevalent in coastal areas. (6) __ is energy harnessed from the ocean or sea . It is produced only when the surface of the water is rough This energy is renewable , environment-friendly and causes no harm to the atmosphere. It can be harnessed in coastal regions of many countries and can help them reduce their dependence on other sources of power. Most of the cities and towns in the world rely on (7) __ derived from the energy of falling or fast-running water to generate electricity. In the early 21^st century it was the most widely utilised form of a renewable energy. (8) __ is produced from organic material (e.g.plants, such as corn and soy) and is commonly used throughout the world . Plants convert light energy into chemical energy and the energy from these organisms can be burned to create heat or converted into electricity. (9) __ is produced through the process of nuclear fission 10. It is a great subject for debate as to how safe it is and whether or not it is really energy efficient when you take into account the waste it produces . But it still remains one of the major sources of energy today which provides 17 percent of the world's electricity.
