Proponents of alternative energy argue that renewable energies and/or nuclear energy are cleaner than fossil fuel energies, they won''t run out, and the maintenance requirements are lower. Additionally,
While hydropower is theoretically a clean energy source replenished by rain and snow, it also has several drawbacks. Large dams can disrupt river ecosystems
2) Wind Energy. Wind can be another alternative energy source which continues to be supplied by Mother Nature without any subsequent cost. The initial upfront cost will pay itself off in a reasonably quick timeframe. Wind power can be made use of in South Africa. It''s especially effective in windy areas like Cape Town.
Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time. The major types of renewable energy sources are: Download image U.S. primary energy consumption by energy source,
It is a highly energy-dense fuel, making it efficient for various applications. Cons: 1. Environmental Impact. The extraction, transport, and combustion of oil can result in spills, air pollution, and habitat disruption. 2. Finite Resource. Like other fossil fuels, oil is finite and will eventually run out.
For the purpose of this discussion on the advantages and disadvantages of alternative energy, the sources that fit this definition are solar, wind, hydroelectric, geothermal, and
Disadvantages of Alternative Energy. High cost. Unfortunately, the technologies that utilise alternative sources of energy remain relatively expensive. This of course has a major influence on the prices of energy which in turn causes concerns about adverse economic effects. A large segment of industry depends heavily on cheap energy in order

4 · Renewable energy, usable energy derived from replenishable sources such as the Sun (solar energy), wind (wind power), rivers (hydroelectric power), hot springs (geothermal energy), tides (tidal
Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Non-renewable energy, in contrast, comes from finite sources, such as coal, natural gas, and oil.
Wind energy in the United States helps avoid 336 million metric tons of carbon dioxide emissions annually. (link is external) —equivalent to the emissions from 73 million cars. Wind power benefits local communities. Wind projects deliver an estimated $2 billion. (link is external) in state and local tax payments and land-lease payments each year.
1. Alternative energy will never run out. The first and most important benefit of using renewable energy is in its name – it is renewable. It means that it will not run out. Ever. While fossil fuels will run out in 40-60 years, the sun will always shine, the wind will always blow, and the Earth will always have geothermal energy.
Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly
Vocabulary. Nonrenewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed
8. Renewable Energy Can Increase Countries'' Economic Independence. Countries with no fossil fuel resources can reduce their energy dependence with a distributed network of renewable energy technologies. In fact, local people can generate electricity using renewable technologies and help governments reduce oil imports.
Cons: There is impact on environment. Can potentially pollute the air, soil, and water bodies. The burning of coal emits CO2, SO2, toxic heavy metals, cadmium, arsenic, and mercury. "Clean Coal" involves costs. Coal source is finite. Byproducts of coal mining include arsenic, SO2, selenium, and mercury. 3.
Here are some of the top benefits of using an alternative energy source: Renewable energy won''t run out. Renewable energy has lower maintenance
