Renewable Energy (Solar And Hydro) Research Assignment

2624 words - 10 pages

-Research 2 different types of renewable energy sources and list: where and when they have been used, how they produce electricity, facts and stats, environmental impact, advantages and disadvantages.Solar and hydro power are advantageous, easy to acquire and eco-friendly sources of power. They are two excellent forms of renewable energy. A great advantage of these sources is that their energy does not need to be generated on a large scale and transmitted over a grid system like the energy produced by using fossil fuels. You can create just enough solar electricity to power your house or just enough hydroelectricity to power a small community. Solar energy depends upon the heat and light energy of the sun and is used to do more than just create electricity. Hydroelectric energy is a renewable energy source that depends upon the hydrologic cycle of water. Hydroelectric power is a very important source of electricity for Canada, as we get nearly 2 thirds of our energy from hydro dams.When and where solar and hydro sources have been usedSolarSolar energy has many uses. From the earlier days, where the ancient Greeks used sundials to tell time, all the way to the more advanced uses of solar energy today. Light energy from the sun is used to power most satellites. This is especially efficient because it is a free source of energy and even though on earth we can't always use solar energy all the time, that is not the case in space. Other ways that we use the sun's light energy is to power communications stations at the top of mountains and navigational buoys at sea. The most important way that we use solar power is to generate electricity. Photovoltaic cells can generate electricity to pump water, charge batteries, power road signs, run weather stations and are also used in most new calculators.There is another type of energy from the sun, which is also very useful. This is the HEAT energy from the sun and it is used for heating water in homes, commercially or for agriculture. It is used to heat swimming pools and for the ventilation of air and buildings. The heat energy from the sun is also used to cool buildings, or detoxify air and water (desalination, turn saltwater into fresh drinking water). Other than this, we use the sun's energy in simpler ways, like warming ourselves up or drying clothes on a clothesline.Solar energy is helpful, but it's not that efficient. On earth, clouds absorb sunlight reducing solar power generation. In addition to that, at nighttime, solar power is useless because the cells, or collectors, get no light or heat energy from the sun. In space, we'd be able to generate electric power at night as well, because these problems don't exist. But since they do on earth, the best times that solar energy can be used is on sunny days, where there is hardly any cloud cover. Solar electricity cannot be stored; this means that buildings etc. that are connected to a solar power source also have a backup connection to the grid. Just in...
