What else can I help you with?
A material on earth that is necessary or useful to people is?
Such materials are known as "natural resources".
Is electricity is natural or man made?
Both. Some kinds are natural and some man-made.
Kinds of elictricity?
There are two main types of electricity: direct current (DC) and alternating current (AC). DC flows in one direction and is commonly used in batteries and electronics. AC changes direction periodically and is used in homes and businesses for powering appliances and lighting.
What kinds of energy are used to make a hockey stick?
The energy used to make a hockey stick typically comes from electricity and natural gas for manufacturing processes such as molding, shaping, and finishing the stick. Additionally, renewable energy sources like solar or wind power may also be used in some manufacturing facilities to reduce environmental impact.
How is tidal power delivered to consumers?
There are two kinds of tidal power stations: * Tidal stream systems, which use turbines turned by the moving water to generate electricity. Very like wind power. * Barrage systems. These are like dams built across rivers. After the tide comes in, the gates are closed. When the tide is low enough on the downstream side, the water flows through turbines rather like a hydro-electric dam. Barrage systems are expensive to build and maintain. They create problems for fish, swimming through the turbines, and they may encourage more sediment built up behind the barrages. If Tidal power stations are replacing fossil-fuel-burning power stations, then they are a positive effect on the environment. No carbon dioxide, obviously, is produced from tidal power stations. They are a renewable source of energy as long as the water keeps moving.
Renewable energy comes from natural resources that can be used up What are two kinds of renewable energy?
Your question is not correct. Renewable energy comes from natural resources that are NOT used up. That's why it is called renewable.Two kinds of renewable energy that can be captured to generate electricity are:solar powerwind power.
What are kinds of renwable resources are there?
there are many renewable resources, for example wind is a renewable resource and so is light
One kind of renewable resource from the Ocean is?
There are many kinds of renewable resources from the ocean. One of these renewable resources includes any of the oceans plant life.
Two kinds of renewable energy from natural resources?
Two examples of renewable energy from natural resources are solar power and wind power. Solar power harnesses energy from the sun using photovoltaic cells, while wind power uses wind turbines to generate electricity. Both sources are abundant, clean, and sustainable alternatives to fossil fuels.
Types of energy resources?
there are three main kinds of energy. these are renewable, nonrenewable, and inexhaustible. renewable resources are resources that can be replaced over time. non renewable resources are resources that can not be replaced in a reasonable time. inexhaustible resources are resources that are constantly produced.
What are two kinds of resources found on the Earth?
Two kinds of resources found on Earth are renewable resources and non-renewable resources. Renewable resources, such as solar energy, wind energy, and biomass, can be replenished naturally over time. In contrast, non-renewable resources, like fossil fuels and minerals, are finite and can be depleted as they are consumed. Both types of resources are essential for human development and energy production.
What are some non-renewable resources in Finland?
There are several kinds of non renewable resources in Finland. There are fossil fuels such as petroleum, coal, and oil.
What resources are both renewable and non-renewable?
There is no single thing that is renewable and non-renewable at the same time. That's a contradiction in terms. Some kinds of wood (fast growing pine plantations, for example) are renewable, while other kinds of wood (teak and mahogany, perhaps) are non-renewable as they take very many years to grow again.
What are 3 kinds of inexhaustible kinds of energy?
Three examples of inexhaustible sources of energy are solar power, wind power, and geothermal energy. These sources are continuously replenished by natural processes and can be harnessed to generate electricity without depleting the Earth's resources.
How can solar energy be used to power objects instead of fuel?
Solar energy can be used to generate electricity, which will then drive machinery of all kinds, including vehicles. Most fossil fuel (coal, oil and natural gas) is also used to generate electricity.
What kinds of renewable energy are there?
Renewable energy comes from a renewable source, that is, that keeps on coming, like sun, wind, tides, ocean waves and geothermal heat (from deep under the ground).Non-renewable energy comes from burning fossil fuels like oil, coal, wood and nuclear power. When we've used them all, there's none left.So the renewable energy that we are harnessing is:Solar Power (using the sun to heat water and generate electricity)Hydro-electric power (from damming rivers)Wind Power (using wind turbines to generate electricity)Tidal Power (using the power of the tides to generate electricity)Ocean Wave Power (using the power of the waves to generate electricity)Geothermal Power (using heat from deep under the earth)Ocean Thermal Power (using the difference in temperature of surface and deep water) Biomass which is:producing biofuel like ethanol from vegetation.producing biogas by capturing methane (natural gas) from landfill sites and from animal and human sewage. * using vegetation to burn in steam generators. Burning it will release (very recently captured) carbon dioxide, but if we allow the vegetation to decompose it releases methane, a much more dangerous greenhouse gas.
What kinds of things can wind energy be used for?
Wind energy can be used to spin a pinwheel, generate electricity, ruffle a skirt or a flag, or propel a sailboat.
