Define sustainability with respect to energy conservation
Answers
Answer:
Sustainability means that a process or state can be maintained at a certain level for as long as is wanted. ... The Commission defined sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."
Answer:
Sustainable energy or clean energy is the practice of using energy in a way that "meets the needs of the present without compromising the ability of future generations to meet their own needs." ... In general, renewable energy sources such as solar, wind, and hydroelectric energy are widely considered to be sustainable
Explanation:
Types of Sustainable Energy
Sustainable energy are not just a part of renewable energy sources, they are also the sources of energy that can best be used to power homes and industries without any harmful effects being experienced. This is the sole reason why many people advice the use of these forms of energy in everyday life. It is because its effects to the environment are purely beneficial.
Solar Energy Solar energy is the best form of sustainable energy. This energy manifests itself in tow forms. There is the light and the heat. Both of these forms are equally important to us in our day to day living and other forms of life. For instance, the plants need the light to grow and generate food while man needs the heat energy to maintain body temperature and power their homes and industries. This means that it is the greatest form of sustainable energy. It can be used two folds with greater results as needed. This only serves to generate confidence and ensure that we live the way we intended without causing further harm to the environment.
Wind Energy Wind is a sustainable energy source. It is available naturally and can be tapped to produce vast amounts of power that can be used in many ways and places. For instance, sailors tap this energy to help the ship propel through its various directions to distant shores for trading. Nowadays, this energy sources is being commercialized. There are many companies that have invested heavily on power grids and windmills to tap into this energy source. The energy generated can be sold to other people to power their homes and industries. In the near future, sustainable energy like wind power will be a big industry and the fossil fuels exploration will have halted and no longer being used.
Geothermal Energy Geothermal energy allows us fetch the energy from beneath the earth. This occurs by installing geothermal power stations that can use heat coming out from inside the earth and use it to generate electricity. The temperature below the earth around 10,000 meters is so high that it can used to boil water. Geothermal energy cannot be harnessed everywhere as high temperature is needed to produce steam that could move turbines. It can be harnessed in those areas that have high seismic activity and are prone to volcanoes. They are environment friendly and can produce energy throughout the day but their ability to produce energy at suitable regions restricts us from using it on a much wider scale.
Ocean Energy There is massive size of oceans in this world. About 70% of the earth is covered with water. The potential that ocean energy has to generate power is much higher than any other source of energy. This sustainable energy allows us to harness it in 3 ways i.e. wave, tidal or ocean thermal energy conversion (OTEC). Tides have immense power which when effectively tapped can generate a lot of energy and can be used to power millions of homes. Waves produced at the oceans can be used by ocean thermal plants to convert the kinetic energy in waves to mechanical energy of turbines which can again converted to electrical energy through generators. Setting up of big plants at ocean may cause ecological imbalance and disturb aquatic life.
Biomass Energy Biomass energy is produced by burning of wood, timber, landfills and municipal and agricultural waste. It is completely renewable and does not produce harmful gases like carbon dioxide which is primarily responsible for increase in global warming. Although, carbon dioxide is produced by burning these products but that is equally compensated when plants take this carbon dioxide and produce oxygen. It also helps to reduce landfills but are not as effective as fossil fuels.
Hydroelectric Power On the other hand, there are the rivers or waterfalls whose energy of the moving water is captured that can turn turbines to generate power. This is commonly known as hydroelectric power. It is very common nowadays and it is powering most parts of the world and one of the biggest form of alternative energy currently being used. There are many companies and countries that are exporting this energy to other countries who unable to harness it on their own due to lack of the necessary resources or conditions. The energy is commonly transported in form of power lines to various parts of the country and even outside the country.
