It is only available during the day; if it is cloudy or overcast, there is no sunlight to be exposed, therefore a way to collect the sun energy to be used on those days have to be put in place. Question: In your opinion, from what sources does a sustainable society obtain its energy needs? Taking into consideration conventional and alternative sources, discuss each in its long term sustainability. In a sustainable society, the sources that energy is obtained from are renewable energy sources. The sun, the wind, geothermal, and water.
The mechanical power is converted into electricity to power homes and businesses. Wind plants produce electricity that emits zero pollutants. The environmental concern from the wind power plants is minimal; the problems that arise are the noise created from the rotator blades and the killing of birds by flying into the blades. With some technological advances, that issue was drastically reduced. Another major challenge is that the wind does not blow all the time, therefore, the turbines do not spin and no power is created during these
There is lots of renewable energy such as solar energy, wind energy, geothermal energy and hydroelectric energy. There are many benefits of alternative energy. Most of alternative energy is friendly to environment and people. They will not consume fossil fuel and cause almost no air pollution, so they will not harmful environment. Harnessing of renewable energy is keeping the world from running out of energy, delays and decrease greenhouse effects and global warming because using renewable energy can
Should Australia go Nuclear? Unless you live under a stone, you’ll be aware that we have a very serious problem with global warming, most of which occurs because of the burning of fossil fuels like coal to produce energy. As a result of these concerns, there is a really important debate currently underway about what kind of energy Australia should have in the future, fossil fuel, renewable energy or nuclear? Nuclear energy was on the discussion table a few years ago but recently it has surfaced again due to global warming. One of the greatest advantages of nuclear power is that it avoids the wide variety of environmental problems arising from burning fossil fuels such as coal, gas and oil.
It is time for Australia to embrace nuclear energy. Embracing nuclear energy doesn’t necessarily mean making it our only power source but maybe combining it with renewable energy sources. There are various reasons why Australia should take on nuclear energy. Firstly Global warming is a big issue that affects the globe. Every year global warming looms larger and nuclear energy is one clear way to cut emissions.
Solar energy benefits outpace the concerns of drilling by a landslide. The time has come to put the drill aside and use are natural tools to energize our country. Coal, oil, and natural gas are the primary non-renewable energy sources being utilized in the United States today. These resources, also known as fossil fuels, are damaging the natural environment that we live in carrying great consequence. According to Klare (2010) “It may not seem as if we operate under such a philosophy today, but we do—one that extols growth over all other considerations, that privileges existing fuels over
You can build your own electricity generator by using solar panels. When you generate your own solar power, you don't have to deal with any bills from the utility company. Besides, a big benefit to use solar technology is that it is a renewable and clean type of energy. Solar power cannot create large amounts of CO2 that fossil fuel can. In other words, I believe
Solar energy is a non-pollutant, cost effective, maintenance free, life span of up to 40 years; however the upfront cost is enormous, and not everyone can afford the cost to put the stylish panels on their roof tops. Many jobs would be lost at the oil field however more jobs would be created by installing other methods of
By having helium-3 as the next power production on earth it will also decrease the amount of pollution and radioactive waste in the atmosphere. Nuclear power which involves the process of fission has provided
What happens to the waste? For example, nuclear energy does not produce smoke or carbon dioxide so it does not contribute to air pollution. (Technology Student ,2009) Nuclear power is characterized by the very large amount of energy available from a very small amount of fuel. The amount of waste is also relatively small. However, much of the waste is radioactive and therefore must be carefully managed as hazardous waste.
