Renewable Energy Resources
可再生能源资源
1.漂亮的裙子怎么画Introduction
引言
Some sources of energy are known as renewable energy resources.This is becau,unlike non-renewable energy resources,they will not run out.
一些能源被称为可再生能源资源。这是因为,不像不可再生能源资源,他们不会用完。
Renewable energy resources include solar energy,geothermal energy,energy from the wind or waves,energy from tides and energy from biomass.
可再生能源包括太阳能、地热能、风能或波浪能、潮汐能和来自生物的能量。
2.Solar energy
太阳能
Every year the earth receives about 3*1010 billion kilojoule of energy. This energy drives procesd in the atmosphere that cau the wind and waves.
每年地球接收大约3×1011亿千焦耳的能量。这种能量驱动在大气中处理,导致风和波浪。
Some energy is absorbed by green plants and ud to make food by photosynthesis.So ultimately,the sun is source of most energy resources available to us,including fossil fuels.
一些能源被绿色植物吸收,并用来通过光合作用制造食物。因此,最终,太阳是我们提供给我们的 我们可以获得的 大部分能源资源的来源,包括化石燃料。
Scientists also try to u the energy of the sun directly.This we call solar energy.“Solar”means“sun”.
科学家们也尝试直接利用太阳的能量。这我们称之为太阳能。“太阳”的意思是“太阳”。
Solar energy can be ud to heat fluid such as water in solar collector panels.Simple types u flat collector panels mounted on a south-facing roof or wall,each with transparent cover to admit sunlight.
太阳能可用于加热流体,如太阳能集热板中的水。简单的类型使用平板收集板安装在一个南面临的屋顶或墙壁,每一个透明的盖承认阳光。
3.请给我一个拥抱Geothermal Energy
地热能源
工程管理专业排名手机怎么隐藏软件Geothermal energy is the natural heat of the Earth”s crust.The temperature at the Earth”s core is over 70000℃.
地热能是地球地壳的自然热。地球的核心温度超过70000。
The rocks,not too far below the surface,are also quite hot,perhaps at 500℃ about 1 km down.
岩石,地表以下不远处,也相当热,也许500℃左右约在1公里以下。
In some areas there are “hotspots”where the temperature below the surface is higher.This is usually near where the earth”s tectonic plates meet.The existence of hot springs,geyrs and volcanoes points to evidence of hot rocks below the surface.
在某些区域有“热点”,这些热点以下的温度较高。这通常是在地球的构造板块相遇的地方。温泉的存在,间歇泉和火山指出地表以下温度很高的证据。
4.Wind Energy
风能
When the Earth is irradiated by the Sun the ground absorbs some of this radiation.This heated ground warms the air above it.Hot air ris in what are called convection currents.The uneven heating of the earth”s surface caus winds.
会呼吸的痛吉他谱当地球被太阳照射时,地面吸收了一些这种辐射.这个被加热的地面温暖了上面的空气。热空气上升,被称为对流。地球表面的不均匀加热会引起风。
For example,if the Sun”s rays fall on land and a,the land heats up more quickly.This results in the air above the land moving upwards more quickly than that over the a hot air ris .
例如,如果太阳的光线落在陆地和海洋,土地更迅速地加热。这导致在陆地上方地空气向上移动的速度比在海上快 热空气上升 。分数怎么打
As a result the colder air over the a will rush in to fill the gap left by rising air.It is process like the that give ri to high and low pressure areas,and thus to winds.
因此,海上的冷空气将冲进来,以填补上升空气留下的空隙.它是这样的过程,引起高压和低压区之分,从而形成风。
5.Tidal Energy
潮汐能
Tides are caud by the gravitational pull of the Moon,and to a lesr extent the Sun,on t
he oceans around the world.The difference between high tide and low tide can be many meters,and the energy of the tidal movement can be ud to generate electricity.
在世界各地海洋的潮汐是由月球的引力引起的,并在较小程度上来自太阳的影响。高潮和低潮的区别可以有很多米,潮汐运动的能量可以用来发电。

水电能源
Flowing rivers have kinetic energy.This energy can be collected and ud. Hydroelectric power is generated by the falling of water through a turbine.
流动的河流有动能。这种能量可以收集和使用。水力发电是由涡轮机的水通过下降而产生的。
If a dam is built across the river,water can be allowed to flow in a controlled way through turbines that generate electricity.
如果一个大坝建在河上,水可以被允许通过涡轮机,发电的控制方式来流动。便利商店4
7.Energy from Biomass
生物质能源
Biomass is material from living things.This could be plant material,animal material or even bacteria.Organic matter can be burned to provide heat,or fermented to produce gas.
生物量是生物物质的材料。这可能是植物的物质,动物的物质,甚至是细菌,有机物可以被燃烧以提供热量,或发酵产生气体。
Plant material such as wood or hay can be burned to provide heat to rai steam and so generate electricity in a power station.
植物的材料,如木材或干草可以被烧以提供热量来提高蒸汽量,从而在发电站发电。
Animal Animal slurry from a farm can be treated to provide gas that can be burned to generate electricity.Landfill sites emit gas mainly methane that can also be u
d to provide energy.Some plant materials such as sugar cane and maize sweet corn can be fermented to produce alcohol.Alcohol can be ud in cars as a substitute for petrol.
动物废物 例如从农场的动物浆 可以被处理,以提供可以被烧成发电的气体。填埋场发出的气体 主要是甲烷 ,也可以用来提供能源。一些植物材料,如甘蔗和玉米 甜玉米 可以发酵生产酒精。酒精可用于汽车作为汽油的替代品。
