Can manure make energy?

Yes, you can replace non-renewable substances (like coal, oil and gas) with manure, you burn the manure the same way you'd burn non-renewable sources to make energy. Like this the manure is known as biomass or biofuel.

Manure can also be used to manufacture methane, which is the same as natural gas.

How does hydro-power energy affect the environment?

Hydropower energy can have both positive and negative environmental impacts. On the positive side, it is a clean and renewable energy source that does not produce greenhouse gas emissions. However, the construction of dams and reservoirs for hydropower can disrupt ecosystems, harm wildlife, alter water flow patterns, and displace communities. Managing these impacts is crucial to ensure sustainable hydropower development.

How does hydroelectric energy impact the earth?

Hydroelectric energy can have both positive and negative impacts on the Earth. On the positive side, it is a renewable energy source that produces minimal greenhouse gas emissions. However, constructing large dams for hydroelectric power can disrupt ecosystems, alter river flow patterns, and displace communities. Mitigation measures and careful planning are needed to minimize these negative impacts.

Is hydroelectricity good for the earth?

Hydroelectricity is a renewable energy source that produces minimal greenhouse gas emissions and has low operational costs. However, the construction of dams can have significant environmental impacts, including altering ecosystems, disrupting fish migration, and affecting water quality. Efforts to minimize these negative effects, such as improving fish passage systems and sediment management, can help make hydroelectricity more environmentally friendly.

What happens when a dam leaks or over flows?

Down stream following the normal course of the river or stream that was blocked. The wall of water will scour anything in its path and destroy and damage homes buildings crops and anything else that is in the way. Usually it will be well above the flood stage for the area and cause a great deal of damage.

What is hydro geological resource?

Hydrogeological resources refer to natural sources of water that can be extracted from the ground for human use, such as groundwater stored in aquifers. These resources play a crucial role in supplying fresh water for drinking, irrigation, and industrial purposes. Understanding the hydrogeology of an area is important for managing water resources sustainably.

What effects does hydro energy have on the planet?

Hydro energy has positive effects on the planet as it is a renewable energy source that generates electricity without emitting greenhouse gases. However, the construction of dams for hydroelectric power can disrupt ecosystems, alter water flow, and displace communities. Overall, hydro energy is considered a relatively clean and sustainable energy source.

How power plants generate electrical energy from kinetic energy?

Power plants generate electrical energy from kinetic energy by using a turbine to convert the kinetic energy of steam or falling water into mechanical energy, which then drives a generator to produce electricity. The spinning turbine is connected to a rotor in the generator, causing it to rotate and create an electromagnetic field that generates electricity.

How is hydropower good for the earth?

Hydropower is a renewable energy source that produces electricity without greenhouse gas emissions, which helps to reduce the impact of climate change. It is also a reliable and predictable source of energy, and the reservoirs created by hydropower dams can provide recreational opportunities and water storage for irrigation.

Why Is Hydroelectric Energy Bad For the Earth?

Hydroelectric energy can have negative impacts on the environment due to the disruption of natural river flows, which can harm aquatic ecosystems and fish migration patterns. The construction of dams and reservoirs can also lead to habitat destruction and displacement of communities. Additionally, methane emissions from decomposing organic matter in reservoirs can contribute to greenhouse gas emissions.

A mountainous region would be a likely source for what energy?

A mountainous region would likely be a good source for hydropower energy due to abundant flowing water that can be harnessed for hydroelectric power generation.

Why do hydro electric power stations need to be located at dam walls?

Hydroelectric power stations need to be located at dam walls to take advantage of the potential energy created by the difference in water levels. Water stored in the reservoir behind the dam can be released and flow through turbines located at the base of the dam, generating electricity as the water flows downhill. This setup allows for the conversion of gravitational potential energy into electrical energy.

Where is Tidal Energy found on Earth?

There is a large tidal energy scheme at Rance in northern France. There are smaller ones in other parts of the world. Tidal mills were once fairly common in Britain. Tides are caused by the gravitational forces of the moon. These forces translate into high and low tides, on the earth. Tidal energy is transferred from the moon to the earth by tidal torque. This results in tidal lock. This is why you always see the same side of the moon

How is water use to make electricity?

Water is allowed to fall from some height into a turbine. The height the water falls increases its kinetic energy. That is why dams are so tall. The turbine rotates. the turbine is mounted on a shaft. The shaft is connected to the shaft of a generator. When the generator is spun by the turbine, it makes electricity.

Water actually does not fall but rather flows down stream at high velocity and great pressure.

it also saves much more money and if we only use it we will be stoping polution and we can reuse it.

The gas waste generated by many power plants is?

primarily composed of carbon dioxide, sulfur dioxide, and nitrogen oxides. These pollutants are released during the combustion of fossil fuels, contributing to air pollution and climate change. Measures such as implementing cleaner technologies and capturing and storing emissions are being developed to address this issue.

How much electrical energy does wave power produce?

A recently proposed wave energy power system off the south western coast of Africa estimated their construction cost to be $2.9-million per MW.

The most cost effective wave energy generation plants are operating around 7.5 cents per kWh, as opposed to coal fired power stations at 2.6 cents/kWh.

What are the advantages of tidal barrages?

Tidal barrages can generate predictable and reliable electricity by harnessing the kinetic energy of tides. They have a long operational life of up to 100 years and produce no greenhouse gas emissions during electricity generation. Tidal barrages also offer potential for flood protection and navigation improvements.

How hydropower generates energy?

Hydropower generates energy by converting the potential energy of water stored in reservoirs or flowing in rivers into kinetic energy. This kinetic energy is used to turn turbines, which then drive generators to produce electricity. The movement of water is a renewable energy source that does not emit greenhouse gases, making hydropower a sustainable option for generating electricity.

When you use electricity from the water will it reduce the amount of water?

No, using electricity generated from water (hydropower) does not reduce the amount of water in the river or source, as the water continues to flow downstream after passing through the hydropower plant. Hydropower is a renewable energy source that harnesses the energy of flowing water to generate electricity without depleting the water resource.

What minerals that are will bubble when treated with hydroelectric acid?

Minerals that will bubble when treated with hydrochloric acid typically contain carbonate minerals, such as calcite or dolomite. The reaction between the acid and carbonate minerals releases carbon dioxide gas, which creates bubbles or fizzing.

Why Water is stored in a high reservoir to run a turbine why?

Water is stored in a high reservoir to create potential energy due to its elevation. When the water is released and flows down to run a turbine, the potential energy is converted into kinetic energy, which turns the turbine to generate electricity. Storing water in a high reservoir allows for efficient energy production and control of electricity generation.

Why do you need water to make electricity?

Discounting solar and wind generation. It depends on how you are generating electricity. For example, in your car, you are generating electricity as the engine turns which also turns a generator or alternator to recharge your battery. In a car with a water cooled engine, water cools the engine so it doesn't overheat. In some power generation water is heated to produce steam which in turn might turn a turbine to generate electricity. In other cases a hydroelectric system might use falling water to turn a turbine. In a nuclear power plant water can be used to cool the heat generated by the nuclear fission process.

How much does hydroelectric energy cost per kw?

The cost of hydroelectric energy production varies greatly depending on factors such as location, size of the project, and construction costs. On average, the cost of producing hydroelectric energy can range from $0.03 to $0.09 per kWh.

How is the sun involved in hydroelectric power?

The sun is indirectly involved in hydroelectric power through the water cycle. The sun's energy causes water to evaporate from oceans and other water bodies, forming clouds that eventually lead to precipitation. This precipitation fills reservoirs behind hydroelectric dams, providing the water needed to generate hydroelectric power.
