Coal, oil natural gases are the finite sources available for us. Solar energy is obtained from the radiations of sun. The two main types of solar energy are active solar energy and passive solar energy. It is depend on how they store and distribute solar energy or convert it
“Renewable energy resources that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun or from other natural movement and mechanisms of the environment. Renewable energy does not include energy resources derived from fossil fuels, waste product from fossil sources, or waste products from inorganic sources.” There are a few types of renewable energy sources. 1) Wind Energy 2) Biomass 3) Hydropower 4) Geothermal 5) Solar All electricity sources, renewable and nonrenewable, have advantages and deficiencies. Factors are includes: • Maintenance cost • Feasibility analysis. • Initial cost.
Fossil fuels, based on the article “Today and Tomorrow”, are generally natural resources. From the word itself, fossil, fossil fuels are formed from remnants of prehistoric creatures. Most of the biological matter formed to fossil fuels are from plants and microorganisms. Because of being exposed to vast heat and pressure from the inner sections of the earth through an estimate of one hundred to four hundred million years ago, these biological matters have physically and chemically change to form fossil fuels. Fossil fuels are mainly being used as a source of energy.
This force caused the remains to turn into a dark rock, known as coal(Brown). Coal was an abundant resource used to power machines in Britain. “Everything changed during the Industrial Revolution, which began around 1750. People found an extra source of energy with an incredible capacity for work. That source was fossil fuels — coal, oil, and natural gas, though coal led the way — formed underground from the remains of plants and animals from much earlier geologic times”(Brown).
Still many countries, including the United States, use polluted energy source. These energy sources are nuclear, coal, gas, and petroleum. Every country are able to use clean reliable energy such as hydroelectric, wind, and solar power. These three energy source are able to power the whole world if everyone depended on it. Instead polluted cheap energy source are being
There is a shortage supply of fossil fuel, the construction of new hydroelectric power station is also limited. Hence the nuclear power has shown a fast development. More and more countries have understood the need for nuclear energy. Nuclear energy is the outcome of the nuclear reaction took place in radioactive metals which could be utilized in the form of heat energy. The heat energy produced during the nuclear reaction used to operate steam
Although Venus has a central core, rocky mantle, and solid crust composition similar to earth, the environment within its atmosphere other than its composition is extravagantly different. Venus is 108.2 million kilometers away from the sun and the second closest planet to the sun. The atmosphere of Venus creates a greenhouse effect trapping all the heat in. This leads to Venus having an average surface temperature of 462 degrees Celsius. Crowning it the planet with the hottest surface temperature in our galaxy.
Imagine a world without electricity. Unfortunately, that isn’t possible since the modern world depends on it for almost every aspect of daily living. But energy is required to produce electricity. That energy source is either renewable or nonrenewable. Coal is a nonrenewable resource that is part of the fossil fuel category that includes oil and gas, and it remains a vital source of energy for both industrialized and developing nations.
One of the worst energy sources we use is coal. It’s a dirty energy source that produces less than half of our electricity but nearly 80 percent of all power plant carbon emissions. As mentioned above, coal have been used for hundreds of years. Eliminating that source of energy will lead us to a clean environment and less pollution. But not everyone will agree with the idea of eliminating the use of coal because it’s been used daily for mostly everything.
In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this. But in nuclear fission, atoms are split into smaller atoms, releasing energy. Actually, nuclear power plants can only use nuclear fission to produce electricity. Nuclear generation is the only source of electricity that can produce large amounts of power known as base load power—reliably without emitting greenhouse gases.
