A type of power plant that has developed in the second half of the 20th century. It uses the process of nuclear fission in order to generate electricity. They do this by using nuclear reactors in  combination with the Rankine cycle, where the heat generated by the reactor converts water into steam, which spins a turbine and a generator.

# data[].attributes.body
Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma.

Nuclear powers provide a lot of energy, which generates electricity. Nuclear fuel is a relatively cheap, concentrated energy resource. The fuel for a nuclear power station is usually uranium and plutonium (radioactive materials).

Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity.

# data[].attributes.body
Three mutual conversions of energy forms occur at nuclear power plants: nuclear energy is converted into thermal energy, thermal energy is converted into kinetic energy, and kinetic energy is converted into electric energy.

# data[].attributes.body
Advantages:

Produces a large amount of energy for a small amount of fuel.

Once you put nuclear fuel in the reactor, it can produce energy for 2 or 3  years continuously, we don’t need to put fuel again and again.

No greenhouse gas is emitted while producing Nuclear Energy.

Disadvantages:

Major hazard of Nuclear Power Generation is the disposal of used fuels that are radioactive.

Improper Nuclear Waste storage and disposal results in environmental contamination.

There is a risk of leakage of Nuclear Radiation.

Nuclear fuels like Uranium have limited availability.

Setting up a Nuclear Energy Power Plant has a high cost (initial cost of building the nuclear power station / costs of disposing of the radioactive spent fuel and decommissioning the stations at the end of their working lives.  )

Have to be dealt with very carefully to avoid harm to the surroundings.

Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Inside a nuclear reactor, their radioactive decay is speeded up so that the energy they store is released more quickly. This process is called nuclear fusion: atoms are split apart to form smaller atoms, releasing energy.

Atucha 1 entered commercial operation in 1974. It now uses slightly enriched (0.9%) uranium fuel which has doubled the burn-up from 6 to about 13 GWd/t or more and consequently reduced operating costs by 40%.

Atucha 2 has followed suit. Each has a pressure vessel. Two-thirds of the energy is coming from plutonium, giving it the highest conversion rate of any non-breeder

Embalse In 1967  a larger plant at Embalse in the Córdoba region, 500 km inland appeared. The Embalse plant entered commercial operation in 1984, running on natural uranium fuel. It operated continuously until December 31, 2015 when its first operating cycle ended and the Life Extension project began. The plant successfully brought its reactor to critical on January 4, 2019, initiating the second operating cycle for a 30-year cycle.

A wind farm is a group of wind turbines that transform wind energy into electrical energy. Wind farms can be located on land or offshoreA wind turbine captures the wind, which then produces a renewable energy source

Wind is actually a form of solar energy. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid.

# data[].attributes.body
Advantages: Wind power is cost-effective. Its a clean fuel source. It is sustainable. Wind turbines can be built on existing farms or ranches.

Disadvantages: The wind is inconsistent. Wind turbines are very expensive. It may reduce the local bird popullation. They can be safety hazard. Electricity from wind energy must be stored (eg. batteries). Wind turbines are a potential threat to wildlife such as birds and bats. Deforestation to set up a wind farm creates an environmental impact.
Wind Farms are very noisy. People cannot live nearby.

# data[].attributes.body
A wind turbine transforms the KINETIC  energy of wind into electrical energy. ( IN THE GENERATOR)  A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion. Turbines capture the wind, which then produces a renewable energy source.

It was a nuclear accident that occurred on Saturday 26 April 1986, at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is considered the worst nuclear disaster in history both in terms of cost and casualties, and is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima Daiichi nuc.

A large amount of energy was suddenly released, and two explosions ruptured the reactor core and destroyed the reactor building. One was a highly destructive steam explosion from the vaporizing super-heated cooling water; the other explosion could have been another steam explosion or a small nuclear explosion, akin to a nuclear fizzle. This was immediately followed by an open-air reactor core fire that released considerable airborne radioactive contamination for about nine days that precipitated.

Experts estimate Chernobyl could be habitable again anywhere from 20 to several hundreds of years.

In geothermal power hot water is pumped from deep underground through a well under high pressure. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam. The steam spins a turbine, which is connected to a generator that produces electricity. The steam cools off in a cooling tower and condenses back to water.

Edmond Becquerel  discovered the "photovoltaic effect", that allowed  the conversion of sunlight to solar electric energy. This discovery then led to the invention in 1893 by Charles Fritts of the first genuine solar cell formed by coating sheets of selenium with a thin layer of gold. And this lead to the beggining of the  formation of the device we know today as the solar panel.

Russel Ohl, an American inventor on the payroll of Bell Laboratories, patented the world's first silicon solar cell in 1941. This led to the production of the first solar panel in 1954 by the same company. Solar panels found their first mainstream use in space satellites. For most people, the first solar panel in their life was probably embedded in their new calculator.

TIDAL ENERGY

Tidal energy is a renewable energy powered by the natural rise and fall of ocean tides and currents (Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.). During the 20th century, engineers developed ways to use tidal movement to generate electricity in areas where there is a significant tidal range, the difference in area between high tide and low tide. All methods use special generators to convert tidal energy into electricity. The kinetic energy from the natural rise and fall of tides is harnessed and converted into electricity.

# data[].attributes.body
PROCESS

Tidal barrages are usually installed at tidal inlets or estuaries. Tidal energy works via a turbine  like a wind turbine, with blades rotating 12-to-18 times a minute depending on tide strength. During an incoming high tide, water flows over the turbines as the water rises. Then, the water flows back through the turbines as it becomes low tide.

The turbine is connected to a gearbox that turns a generator, creating electricity.Tides are easily predictable.

# data[].attributes.body
ADVANTAGES AND DISADVANTAGES

Tidal energy has a lot of advantages such as:

Tides are easily predictable.

Inexpensive to maintain.

Reliable and renewable source of energy.
