电能可以靠核裂变、水力发电、生物量、风和太阳能产生；轿车和卡车可以通过电或生物燃料运作。
Electricity can be generated by nuclear fission, hydropower, biomass, wind and solar energy; and cars and lorries can run on electricity or biofuels.
生长的生物物质，甚至在贫瘠的土地上，也需要水，发电也是如此。
Growing biomass, even on marginal agricultural land, does require water, as does making electricity.
比起应用于风能、水力发电、生物燃料或者核能，新材料学和纳米技术在太阳能领域的应用将为其成本降低提供更大的超出人们想像的可能性。
The application of new materials science and nanotechnology offers the possibility of cost reductions much larger than can be imagined in windpower or hydropower, in biomass or in nuclear power.
还有风力、水力发电和生物燃料……目前的趋势是他们将消耗更多的能量。
Same for wind, hydro and biomass... the trend is that they will continue to consume more energy.
环保人士警告生物质发电厂会加剧全球变暖后，鲍尔斯委托进行了这项研究。
Bowles commissioned the study after environmental activists warned biomass power plants could add to global warming.
生物电能的产生跟化石燃料的产生的电能相同：生物物质经常被焚烧产热，把水变成蒸汽，然后驱动发电机。
Bioelectricity is created the same way fossil fuel-generated electricity is: Biomass is usually burned to generate heat, turning water to steam and driving an electrical generator.
还有一些污染物会引发电子剥离化学反应，没释放大量抗氧化剂这种生物破坏性反应是不会平息的。
Still more induce biologically destructive electron-stripping chemical reactions that won't quiet down without a copious release of antioxidants.
用生物量取代20%的燃料，发电站将进一步减排20%。
By replacing 20% of their fuel with biomass, power stations can reduce their emissions by a further 20%.
即将到来：生物柴油发电机。
具体方法是将发电站排放出的废气注入到巨大的罐式光合生物反应器中。 这种光合生物反应器其实就是一个装满了藻类植物的大罐子。
The idea is to pump emissions from power stations into photo-bioreactors, which are large tubes filled with algae.
而且还可以为植入皮肤中的生物传感器发电。这听起来像极了Crysis游戏里的某些桥段....
The nanowires could also be used to power biosensors implanted under the skin.
到2009年底，中国小水电总装机约5500万千瓦，成为全球小水电装机最多的国家；风电装机达到2268万千瓦，而且仍保持高速增长；生物质发电装机400万千瓦；光伏发电30万千瓦。
In 2009, China's installed capacity reached 55 gigawatts of small hydropower, 22.68 gigawatts of wind power, 4 gigawatts for biomass, and 300 megawatts-peak for photovoltaic solar power.
潲水油、瓜果皮、烂菜叶，这些厨房常见的垃圾将变身生物柴油、有机肥料或进行发电。
Waste oil, fruit peel and rotten vegetable leaves, which is familiar in the kitchen, will become the bio-diesel, organic fertilizer or biogas to generate electricity.
这将鼓励海上和陆地风力发电之间的竞争，如同太阳能和生物量之间的竞争，这样价格会下降，消费者将受益。
This would encourage competition between offshore and terrestrial wind power, as well as between solar and biomass, and prices would fall, benefiting customers.
例如，欧洲环境署的专家小组建议大量使用生物燃料资源的最好办法不是用于交通燃料，而是用作民用取暖和发电。
For example, the European Environment Agency advisory panel suggests that the best use of plant biomass is not for transport fuel but to heat homes and generate electricity.
根据内燃式燃气发电机的性能参数和对燃气质量的要求，对下吸式生物质气化炉进行了设计。
