How does electricity flow from a power station to your home?

Note that "electricity" doesn't flow, only current does, which is one aspect of electricity. And current is the flow of electrons.

The current created at power plant travels for many miles over long wires called transmission lines. These transmission lines are held up, away from the ground, by giant wood or metal transmission towers through these it reaches houses.

Where is geothermal energy used?

Geothermal energy is used a lot in the Philippines, Italy, Indonesia, Mexico, New Zealand, Japan and China. Aside from large-scale uses such as in Iceland and in big power plants, geothermal energy can be tapped into in smaller levels using heat pumps to cool and heat homes. Because of this, any home can tap into the free energy source it's built upon.

Why is renewable energy important?

Renewable energy is important because it helps reduce greenhouse gas emissions, combat climate change, and promote energy independence by diversifying energy sources. It also helps create jobs, stimulate economic growth, and improve public health by reducing air and water pollution.

What is the future of Geothermal energy?

The earth like our bodies needs to be taken care of. If we keep destroying and polluting it we won't have clean water, clean air or a healthy place to live.

Answer: Geothermal eergy has many advantages in that it is clean and reliable over the long therm. It is however not accesable in all areas of the Earth. It is limited to areas with active vulcanism in the geologically recent past or with specific geological formations. In North America this would be primarily limited to the Rocky Mountains

Examples of renewable energy?

Disadvantages of geothermal energy?

Some disadvantages of geothermal energy include the potential for depletion of reservoirs if not managed properly, the risk of induced seismic activity from injection and extraction of fluids, and high upfront costs for drilling and infrastructure. Additionally, not all regions have suitable geothermal resources for energy generation.

What is a Geothermal?

It is the energy from the core of the earth. In some areas such as Iceland the heat is close to the surface
A geothermal is a system of hotsprings, like the ones presented on the show Man versus Wild with Bear Grylls (Discovery Channel) in Iceland.

What are some renewable energy sources?

The main renewable sources of energy to generate electricity are:

  1. Hydro-power (use of water from rivers, dams, tides and ocean waves)
  2. Wind energy (using wind turbines)
  3. Solar power (using the power of the sun to heat water or produce electricity)
  4. Geothermal (using the heat deep under the earth's crust)
  5. Ocean Thermal (using surface heat and deep cold water)
  6. Biofuel (producing ethanol from organic material like corn and sugar cane husks)

See the Related Questions links for more information about each of these methods of producing energy.

What are the advantages of geothermal?

Geothermal energy is a renewable energy source that has advantages such as being reliable, having a low carbon footprint, and being cost-effective in the long run. It provides a steady and consistent source of power without being dependent on external factors like weather conditions.

Is nuclear reactors using U-235 renewable energy?

No, all the uranium on earth was produced in supernova explosions that occurred more than 6 billion years ago, there is no more arriving on earth (except small amounts in meteors and they got their uranium from the same supernovas as did earth). Without building reactors that burn plutonium if we use up all the uranium-235 it will become impossible to build a nuclear fission reactor (nuclear fusion reactors might become possible someday, but not yet).

Diffreniate rewable from non rewable reasources of energy?

Renewable resources of energy are those that can be replenished naturally and sustainably, such as solar, wind, and hydro power. Non-renewable resources are finite and will eventually run out, such as fossil fuels like coal, oil, and natural gas. Using renewable resources is important for long-term sustainability and reducing environmental impact.

In a hydroelectric dam the movement of a river is used to spin many wheels. The wheels are called turbines. The spinning is used to make electricity. What is the source of this renewable energy?

The source of this renewable energy is water. As the river flows and spins the turbines in the dam, it generates clean and sustainable hydroelectric power. This energy production method is environmentally friendly and does not produce greenhouse gas emissions.

Which pair of resources is renewable?

Solar, water, wind, biomass, etc are the pair of resources that are renewable.

Which is not a renewable energy resources?

Coal is not a renewable energy resource. It is a fossil fuel that is finite and non-renewable, unlike solar, wind, and hydroelectric power which are sustainable and replenishable resources.

Is potential energy renewable?

Yes, potential energy is considered renewable because it is derived from sources that are naturally replenished, such as gravitational, elastic, and chemical potential energy. These sources can be harnessed repeatedly without being depleted.

What is the most abundant energy source capable of being harnessed by humans?

The sun is the most abundant energy source that can be harnessed by humans. Solar energy is renewable, clean, and can be captured using various technologies like solar panels to generate electricity for homes and businesses.

What is electricity created by wind?

Electricity generated by wind occurs when the kinetic energy in wind is converted into electrical energy through wind turbines. The wind spins the blades of the turbine, which, in turn, rotate a generator to produce electricity. This clean and renewable source of energy can power homes, businesses, and communities.

Why will the use of renewable energy probably keep increasing?

The use of renewable energy is likely to keep increasing due to growing concerns about climate change, decreasing costs of renewable technologies, and government incentives and policies promoting clean energy. Additionally, advancements in renewable technology and energy storage are making renewables more reliable and efficient.

How long is a wind turbine rotor blade?

The length of a wind turbine rotor blade typically ranges from about 100 to 300 feet, with the average being around 150 feet. The size can vary based on the specific turbine model and manufacturer. These large blades are designed to capture the maximum amount of wind energy efficiently.

Why is a windmill not a perpetual motion machine?

Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power.

Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.

What is a non renewable energy?

Non-renewable energy is energy derived from sources that are finite and will eventually deplete, such as fossil fuels like coal, oil, and natural gas. Once these resources are used up, they cannot be easily replenished within a short period of time, making them unsustainable in the long run.

Which is better for the environment - coal or tidal power?

Tidal power. Coal has a massive effect on the environment because burning it releases carbon dioxide, a greenhouse gas which is causing global warming. Tidal power has minimal impact on the environment.

Why sugar canes will not run out?
