Electrical Generation

Electricity generation is the process of generating electrical power from other sources of primary energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet. For electric utilities, it is the first process in the delivery of electricity to consumers. The other processes, electricity transmission, distribution, and electrical power storage and recovery using pumped-storage methods are normally carried out by the electric power industry. Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.

As the nucleus hits the uranium atom, it splits into other pieces repeating the same process creating a chain reaction.

How does it compare to fossil fuels?

Nuclear energy has a longer use expectancy.

Nuclear power has little affect in the environment but, fossil fuels have possibly catastophic dangers

Fossil Fuels create harmful carbon dioxide gases that Nuclear Energy does not create, Using fossil fuels creates greenhouse gases, acid rain and, pollution through oil spills., Using Nuclear Energy creates no green house gases and releases no carbon dioxide into the air

Over long regions could have catasrophic affects but fossil fuels are only catastrophic in smaller regions not long regions.

Nuclear energy has a potential weapon threat while fossil fuels do not.

This is simply a clean and efficient way of boiling water to make steam which drives turbine generators. Except for the reactor itself, a nuclear power station works like most coal or gas-fired power stations.

There is almost an unlimited source of fuel for nuclear energy considering that there is plenty of uranium on earth.

Nuclear power is best more towards europe and Asia.

France gets three quarters of its power from nuclear energy.

Little affect on global warming.

Tidal power plants can injure or kill migrating fish however this can be minimized .

Solar Thermal

The solar thermal process is heating something without external aids, like how the sun heats the water in a swimming pool. Solar panels can be used to capture more heat. Solar panels capture the heat and transfer it into water. The water is then circulated and used to heat the space around it. This is using solar power as heat.

How Solar Power Works

Photovoltaic

PV panels capture the light emmited by the sun and convert it into usable electricity. They do this by exciting the electrons and producing a direct current. This energy can be converted into an alternating current and stored to power homes.

How does it impact the enviornment?

Turbines convert kinetic energy into electrical energy. it is a renewable resource. rotational energy is used to power a generator. the blade or rotor is called a nacelle

Wind power works best in sea based, off shore locations. Oceans allow more constant, strong winds. Costal areas are also good for wind farms because of the ocean winds. Hill tops are excellent because of the altitude. All of these areas are good because they are mostly free of man made interference. http://www.biofuelswatch.com/where-do-wind-turbines-work-best/

It does not creat harmful biproducts like CO2, it uses earths natrul resources so we are cutting down on the use of dangerous fuels to supply energy. Wind in general can detemine and conrol climate and weather. However, it can kill birds and is a noisy destraction to animal life.

Where in the world does it work best?

Hydroelectric power can only be used in certain area however it doesn't have any emissions like fossil fuel. the way in which the energy is made is vary similar to how fossil fuels make energy, both use spinning turbines. Hydro electric energy can effect the wildlife and aquatic life around it.

Geothermal

How does it work?

People use energy to heat thier homes and water, and electricity by digging deep wells and pumping the heated underground water or steam to the surface.

Geothermal energy finds its way to the surface by volcanos, hot springs, and geysers.

How does this method impact the enviorment?

There is almost no impact on the earth., Direct use and heating applications have almost no negative affect

Where in the world does this method work best?

Most active geothermal resources are found on the plate boundaries, The Ring of Fire, In the United Stats geothermal reserviors are located in the west, largest is in California., The largest geothermal power plants are located at the geysers.

Is it good in CT?

It would be a good method for CT but it wouldnt be as good as it would be in Cailfornia.

Compared to Fossil Fuels.

Releases less than 1% of the carbon dixoide.

It is renewable energy.

Geothermal energy is sutainable because it is affected by the earths heat content.

Water

Where in the world does this method work best? Is it good in Connecticut?

Tidal, where ever tides are strong enough. no this method would not work in CT, the tides are not strong enough.

Hydroelectric, This method works where there are large rivers with high drop in elevation. This method has been used in Las Vegas' Hoover dam. this method of electrical generation would could in CT how ever we could not create a Hoover dam we would have to make many micro-hydro power plants. There already many hydroelectric power plans in CT.

Impact on the Environment

Tidal

Hydroeletric, the dam is completely emissions free however it has a tendency to disrupt the aquatic life by either taking away too much oxygen in the water or putting in too much.The dam can also flood near by wildlife habits.

Wave, The magnetic fields produced by the generator disrupts marine life's sensory. The sound emitted by the generator my throw off some birds migratory patterns by scaring them off.

Compared to Fossil Fuels

tidal, Tidal is a renewable source of energy unlike fossil fuels. fossil fuels have a loss of 55% of the energy generated only 20% of energy is lost in tidal power.

Hydroelectric

This method or electrical energy generation will work any when with waves. On the coast of CT this method can be utilized.

wave, There are a lot of differences between fossil fuels and tidal power For one thing, tidal power is more efficient than fossil fuels. Only 20%of energy is is lost during the production of tidal power a number never see by a coal plant most having an average of 55% lost. Also, tidal power is renewable whereas fossil fuels are not renewable. Fossil fuels also create pollution which tidal power does not, it is completely green.

How does it work

Tidal, Tides are created by the gravitational pull of the moon and sun. The theory is that these tides could be used to push turbines to create electricity. One of the tidal power stations is located at the mouth of La Rance River in France. The tides at this river reach a maximum of 44 feet. The dam at this station holds water back until it reaches maximum depth. Then the gates opens to force the water into the river which turns a turbine and generator in the process. The gate then closes and traps the water. At low tide, the gate opens to allow the water to flow out of the river and into the ocean while turning the turbine and generator. The generator creates electricity through this process.

Hydroelectric, The way a hydroelectric dam generates electricity is though water spinning its turbines. water that is being stored behind the dam pushes though pipes and into a turbine which spins the solenoid around the magnet to produce energy.

Wave, Wave power can be produced in two ways. One way is using floating turbine platforms. Another way is by using the changes in air pressure occurring in wave-capture chambers that face the sea. Wave power is the transformation of energy created by the ocean surface waves, and then the energy captured will be used to do useful work — for example for electricity generation, water desalination, or the pumping of water.

Nuclear

How does nuclear power generate electricty?

Produces 15% of our worlds electricity.

Uses nuclear fission to produce electricity., It is clean, safe, and usually cost-competitive

Fun Facts, Nuclear energy has distinct environmental advantages over fossil fuels, basically all its wastes are contained and managed, nuclear power stations do not cause any pollution.

The process of nuclear fission firstly requires the atom to become unstable, this can be done by bombarding it with neutrons to make it heavier, when the nucleus becomes unstable it starts to oscillate and eventually splits, releasing at least one neutron. This neutron then gets absorbed by another atom causing that top become unstable and split, thus casing a chain reaction. The energy comes from the conversion of nuclear mass into energy, explained by Einstein's equation: E=mC2.

This is inside a nuclear power plant

Where in the world does this work best? Is it good in CT?

The US only gets about 1/5th of our pwer from nuclear energy.

Nuclear energy does work in CT, for years it has supplied almost half of our power., The pay of our nuclear power plant workers in rather high, around the 80,000s.

How does it impact the environment?

Generate a lot of energy with minimal power plants.

Produces materials that can make dangerouse weapons.

It creates radioactive waste., They bury both the low grade and high grade radioactive waste underground in rock formations and salt deposites, in hope of keeping it from hurting our environment for thousands of years.

Dangerous power plant conditions and a good target for terrorists., New node

Minimal air pollution.

Water pollution is potentially serious at mines and mills, but limited due to low uranium requirements; potentially serious at waste disposal sites, New node

Solar

How Solar Energy Impacts the Environment

Solar energy is very good for the environment because it doesn't cause any pollution. It uses a natural resource, the sun, which does not harm the environment.

Comparing Solar Energy to Fossil Fuels

Solar energy is a renewable resource, it is good for the environment, it is costly, it is complicated, and it is a somewhat newer way of generating electricity.

Fossil fuels are nonrenewable, they can cause pollution in the air, it is an easy way of generating electricity, and the fuel was created hundreds of thousands of years ago. Fossil fuels are also less expensive than solar power.
