The sun!!
Windmills capture electricity from a renewable source, the wind, without releasing any greenhouse gas emissions into the atmosphere. The present buildup of greenhouse gases is causing the enhanced greenhouse effect which has caused global warming. Renewable energy is the way of the future!
It would be naïve to say that there is a completely renewable source of energy. The sun, for example, which is the source of all energy on Earth, will form a Red Giant in a few billion years time, and will produce far less energy than it had in the past. Additionally, although wind (which relies on the sun) is renewable per say, machines to make use of wind energy, such as wind turbines, require maintenance et cetera and are in that sense, not *completely* renewable. However, for our purposes, and especially in contrast to Fossil fuels, the Sun, the wind, the tides et cetera are renewable sources of energy. Windmills are machines which convert the wind's energy into another form of energy. They, themselves, are not "renewable *sources," rather they can make use of a 'renewable' source, 'the wind,' to transform kinetic into potential energy.
Energy from the burning of fossil fuels (coal, oil and natural gas) is non-renewable.
Sources do not contribute to needs, they contribute to SUPPLY.Needs are generated by people and industry.
A windmill is a machine with sails or blades, usually four, driven by the wind, originally used to pump water, or grind grain, Windmills were originally just that, a wind-powered grain mill (to turn grain into flour). Many "windmills", for instance those scattered around the Australian outback, are actually "wind pumps" to bring water from to the surface from deep underground. Modern ones are used on wind farms that use the renewable source of energy, wind, to make energy.
Nuclear energy that is the source of sun energy which in turn is the source of fossil and renewable energies.
The SUN!
Windmills are renewable because they use the wind, a naturally occurring and inexhaustible resource, as a source of energy to generate electricity. As long as there is wind, windmills can continue to produce clean and sustainable power without depleting finite resources like fossil fuels.
Windmills help us by converting the energy from the wind into electricity. This renewable energy source is clean and does not produce greenhouse gas emissions like fossil fuels. Windmills also help reduce our reliance on nonrenewable energy sources and contribute to a more sustainable energy future.
Windmills are better for the Earth because they generate electricity from wind, a renewable energy source that does not produce greenhouse gas emissions or air pollutants. Windmills contribute to decreasing our reliance on fossil fuels and help combat climate change by reducing carbon emissions. Additionally, windmills have a low carbon footprint compared to traditional energy sources.
Windmills are primarily used to generate electricity from wind energy. They convert the kinetic energy of the wind into mechanical power, which is then converted into electricity through a generator. Windmills are a renewable energy source that helps reduce reliance on fossil fuels and lower carbon emissions.
Wind Power!
The use of windmills and wind turbines can slow global warming. The energy they produce is renewable, that is, it releases no greenhouse gases. Because we have this renewable energy then a little less fossil fuels (coal, oil and natural gas) have to be burnt. As they are the main cause of global warming this is a good thing.
One disadvantage of using windmills as a source of energy is that they are dependent on the availability of wind. If the wind is not blowing consistently, the energy production can be unpredictable and unreliable. Additionally, windmills can have high upfront costs for installation and maintenance.
Windmills are used to harness the power of wind to generate electricity or grind grains. They provide a renewable source of energy that is clean and sustainable, reducing reliance on fossil fuels and decreasing environmental impact. Windmills also help diversify energy sources, contributing to a more resilient and secure energy system.
The ultimate source of the energy driving it is that coming from the Sun.
Fossil fuels are made of consumable raw materials, once consumed, they can't be reversed.Solar and Wind energy are clean energies, since their energy source (solar and wind) never cease to exist, as they are existing natural phenomena.
