t has to be produced first, and if this is done by burning fossil fuels, it does not help against climate change. But, the hydrogen fuel cell will help against climate change in future, because scientists are trying to find new ways to make hydrogen without using fossil fuels.

Tidal energy has been used since about the 11th Century, when small dams were built along ocean estuaries and small streams. the tidal water behind these dams was used to turn water wheels to mill grains.

The growth of the waves depends on the strength of the wind, its duration, and the open ocean distance (fetch) over which it blows

Ocean waves are created by surface winds.

Europe has a long history of employing tidal forces to generate power, and tide mills dating back to the Middle Ages can be found across the continent. A dam with a sluice was constructed spanning a tidal inlet, or a section of a tidal estuary was turned into a reservoir.

Solar energy is an infinitely renewable resource that uses the sun's rays to generate electricity for use in your home. By going solar, you can reduce your energy costs and lower your dependence on fossil fuels, thereby making your own contribution to a cleaner environment. Generally, the solar energy systems we use work as follows:

When we get electricity from renewable energy sources like wind and solar power, we avoid the carbon dioxide emissions that would have come from burning fossil fuels like coal, oil, or natural gas.

Solar energy is energy that is obtain from the sun. This can be found most common in lights and high tech watches.Solar energy does not work when the sun is not shinning.

The wind turbine is a rotating machine that turns the kinetic energy of wind into mechanical energy. The energy can then be used by machines or converted into electricity and stored.

The short answer to this question is that Geothermal Energy is a type of renewable energy that is generated and stored within the Earth.

They were formed from prehistoric plants and animals that lived hundreds of millions of years ago.

Some coal deposits, however, were formed from freshwater swamps which had very little sulfur in them. These coal deposits, located largely in the western part of the United States, have much less sulfur in them

Fatty acid methyl esters (FAME), known as biodiesel, are products of plant or animal origin whose composition and properties are defined by the European Union in standard EN 14214. There is an exception for the iodine value for Spain, which has been established as 140 rather than the 120 proposed by standard EN 14214.

 The process of converting wind energy to electric energy uses a wind turbine. The wind turbines convert the kinetic energy in the wind into mechanical power. The mechanical power can be used for many things. In the past this meant pumping water, creating ventilation, or grinding food sources. While these things still occur, wind power is also used to generate electricity.      The wind turbine is a tall shaft with several horizontal rectangular blades attached to it. These blades are often covered with stiff material or ratting material. When turned they push against the air, causing pressure, and turning the inner shaft. This shaft connects to a generator which then creates energy.

Solar energy is good for the planet because it is a clean way to produce things we need every day. It doesnt cause pollution because it is nature's own energy and is a 100% renewable resource.

Sunlight is Earth's primary source of energy.

The energy stored in petroleum and other fossil fuels was originally converted from sunlight by photosynthesis in the distant past.[119]

Wind machines were used in Persia as early as 200 B.C

The first windmill for electricity production in the United States was built in Cleveland, Ohio by Charles F Brush in 1888, and in 1908 there were 72 wind-driven electric generators from 5 kW to 25 kW.

The first utility grid-connected wind turbine operated in the UK was built by the John Brown Company in 1954

Biofuelwatch has released a new report, ‘Sustainable Biomass: A Modern Myth’. It explores the certification companies certifying biomass as sustainable, the UK government’s proposed sustainability criteria for biomass, and developer’s ‘promises’ to source sustainable biomass.

Biodiesel can result in significant reductions in a number of air pollutants. In general, reductions are greater as more biodiesel is used, depending on the type of biodiesel (soybean, rapeseed or animal fats) and on the conventional diesel used in the blend.
