Energy Sources and Conservation

Extracts from this document...

Introduction

YR10 PHYSICS Independent Learning Project Energy Sources and Conservation Energy is the capacity for doing work. A lump of coal and a tank of gasoline, together with the oxygen needed for their combustion, have chemical energy. Other sorts of energy include electrical and nuclear energy, and light and sound. Energy resources are stores of convertible energy. A renewable resource is a natural resource that is replaced by natural processes in a reasonable amount of time. Soil, water, forests, plants, and animals are all renewable resources as long as they are properly conserved. Solar, wind, wave, and geothermal energies are based on renewable resources. Solar energy is energy obtained from the suns radiation. Solar heating is widely used for industrial or domestic purposes and is an important renewable source of energy. Solar heaters usually consist of a black (heat absorbing) panel containing pipes through which air or water, heated by the sun, is circulated, either by thermal convection or by a pump. ...read more.

Tidal energy contributes to another renewable resource, which is obtained by harnessing the energy of water waves, wave power. The British engineer Stephen Salter who developed the Duck, a floating boom whose segments nod up and down with the waves, introduced the first wave power scheme in 1974. Another device, developed in Japan, uses an oscillating water column to harness wave power. However, wave power hasn't the potential to be used around the world, as it won't contribute significantly to the world's energy needs. Wind power can also be obtained as a renewable resource for the production electricity on a large scale by using wind turbines. Other simple, ancient ways of using wind energy are to sail ships and power windmills. This is a photo of an Operating wind turbine. Wind turbines are Usually found in large Numbers. A non-renewable resource is a natural resource, such as coal or oil, which takes thousands or millions of years to form naturally and can therefore not be replaced once it is consumed. ...read more.

Conclusion

It is one of the world's three main fossil fuels along with coal and oil. Natural gas is a mixture of hydrocarbons. It is usually transported from its source by pipeline, although it may be liquefied for the transport and storage and is often used in remote areas where other fuels are scarce and expensive. Nuclear fuels are another non-renewable resource. Nuclear energy or atomic energy is energy released from the inner core, or nucleus, of an atom. Electricity can be generated from the energy produced by nuclear fissions. In nuclear power stations, fission takes place in a nuclear reactor. The nuclei of Uranium are induced to split releasing large amounts of heat energy. The heat is then removed from the core of the reactor by circulating gas or water, and used to produce the steam that drives alternators and turbines to generate electric power. Unlike fossil fuels, such as coal and oil, which must be burned in large quantities to produce energy, nuclear fuels are used in very small amounts and supplies are therefore unlikely to be exhausted in the future.

    It can be used in a business. Solar energy can be stored in batteries to light a roadside billboard at night. Or the energy can be stored in a battery for an emergency roadside cellular telephone when no telephone wires are around. Some experimental cars also use PV cells.

    Fat is therefore harder to lose as it produces so much energy. For example, if 10grams of carbohydrate were burnt when an athlete ran 1000 meters, 10 grams of fat would be burnt when the athlete ran 2000 meters. Therefore, twice the amount of work is needed to lose the same amount of fat as carbohydrates.

    The results will also be more valid. Volume of milk measured 5 The volume of the milk measured was not as accurate as it could have been. Use a 50cm3 pipette which has an accuracy of � 0.05cm3 which decreases the inaccuracy by 10%. Also changing the concentration of the substrate will have an effect on the

    The sun makes energy by turning hydrogen gas to helium and it releases energy, which escapes outwards into space (nuclear fusion). When energy from the sun reaches our atmosphere, almost a third is replaced straight back into space. The suns energy helps: * By being a force behind our weather and climate.

    Oil especially is used in the production of other industrial products such as plastics, and the exhaustion of its reserves is certainly an uncomfortable thought. Nuclear fission, involving the splitting of uranium-235 into smaller elements and releasing large amounts of energy, has been used in power plants since 1954.
