全球变暖被定义为地球大气整体温度的逐渐升高，这归因于二氧化碳和其他此类污染物水平的增加所造成的温室效应。
Finding clean non-conventional sources ofrenewable energy sources such as wind power with the use of wind turbines, solar energy, or tidal poweris vital when trying to achieve sustainable development and find alternative sources that do not contribute to the carbon footprint we are leaving on the environment.
风能、太阳能和水力发电越来越受欢迎，随着技术的进步和研究的深入，我们可以找到更好的解决方案，更具成本效益和效率，而不会造成全球变暖和环境污染。
The Effects of Global Warming
使用化石燃料、核电站和其他不可再生能源造成的全球变暖的影响可能包括冰川和冰原融化导致的热膨胀导致海平面上升、海洋表面变暖和温度分层增加。
减少这些全球变暖影响的最好方法之一就是减少使用温室气体化石燃料。When we burn fossil fuels, we increase the levels ofgreenhouse gasses正被引入大气层。
Green Space
“Green space” refers to areas of grass, trees, and other vegetation that are conserved and set apart for recreational purposes typically in urban environments. Many environmental benefits go along with Green space including water quality protection, reduced heat buildup, reduced soil erosion, improved air quality, natural resource conservation, and reduced temperatures.
树木是从空气中去除污染物的天然方法，可以提供更好的空气质量。树木还提供荫凉，同时减少一个地区内的热量积累。绿地还可以吸收雨水，清除污染物。污染物被根和土壤分解。
Urban green spaces can also help transport rainwater that could otherwise flood certain areas. The capability to do this cuts down on the cost of having to find other ways to control water in coastal and flood areas and minimizes the need to build more pipes or holding tanks.
生物质能
Biomass is an energy resource that is developed from organic materials and is used as a renewable source of energy that can be utilized to create electricity and other forms of power. Biomass contains stored energy. Plants are absorbing the sun’s energy through the process of photosynthesis and, when biomass is burned, the energy is released as heat.
Burning biomass does release carbon dioxide into the air but the plants take that carbon dioxide and use it to grow leaves, flowers, branches, and stems. Therefore, the carbon dioxide that is released is being returned to the plants and absorbed.
Biomass can create electricity or be converted into fuel and biodiesel or be fermented to produce ethanol. Biomass reduces our dependence on fossil fuels for the production of electricity, heat, and steam. It is always available and can be renewed. Biomass can also help reduce the number of resources that end up in landfills. Biomass is recycling waste that could be potentially harmful to the environment and it is being turned into something that we can use for sustainable development.
The carbon dioxide emissions are controlled and there are no fumes or emissions that are being released into the air to cause harm or destruction to the ozone layer or increase the effects of greenhouse gasses which contributes to global warming.
水力发电
水力发电是一种自然能源涉及到利用th的能量的能力at can be produced by moving water. The energy from the moving water is then turned into a useful power source which reduces dependence on fossil fuels and other nonrenewable resources and limits the effects we have on to the environment, including reducing the threat of global warming.
The water has to be moving at fast speeds so that it can spin a turbine. The turbine then rotates and powers a generator that produces electricity. There is also something known as pumped storage that is utilized during off-peak times. The water from a lower reservoir is pumped into a higher reservoir and is stored to create hydropower later in the day.
随着时间的推移，水力发电正被越来越多的研究和开发，因为我们试图限制这种清洁和可再生能源对海洋生物的影响。由于水电项目可能产生的流量减少，对水温和动植物的栖息地构成威胁。例如，如果河流中的水量减少，它会大大降低水中的含氧量，这会损害水质。
The damage and effects of hydroelectric power depend on the way that the system is operated. Flow releases should be managed and patterns should be monitored. Voluntary certification programs are also being put in place for companies if they want to help limit the environmental impact they are having while operating the equipment. The certification can contribute to ensuring that the river is flowing correctly, the water quality is good, the cultural resources are protected, and the animals and their habitats are being protected.
结论
许多非常规能源可以用来帮助减少全球变暖的威胁。任何具有成本效益和可再生性的能源，在不向大气排放任何污染物或其他毒素的情况下减少我们对化石燃料的依赖，都是一个良好的开端。
非常规能源包括太阳能、潮汐能、地热能和风能。非常规能源通常来自流动能源，这些资源不能被耗尽或耗尽。随着技术的发展和非常规能源的进步，我们看到未来的成本会降低，对环境的负面影响也会减少。
