Humans have attempted to harness wind energy千百年来。早在900年,波斯人使用风力来研磨谷物。
In recent years, as the climate change crisis has made us question our reliance on fossil fuels, wind energy has made a comeback. There is fierce debate over the truth about wind turbines.
他们有高效吗?他们可以取代化石燃料吗?他们会损害环境吗?
继续阅读以了解这些和其他问题的答案。
What Is Wind Energy?
当空气从高压区域移动到低压区域时,就会发生风。
行星的不对称加热使得这些高压和低压区域形成。由于地球的倾斜,地球的某些部分比其他部分接收更多的阳光。
由于假设行星将总是在其轴上旋转的相当安全,因此假设风将永远发生在地球上也是相当安全的。
风能如何捕获?
Wind turbines capture wind energy.
A wind turbine is a modern version of a windmill. It’s a large structure that supports fan blades high off the surface of the earth. the blades are positioned perpendicular to air flow.
As the wind blows, the air forces the blades to turn.
刀片的转弯激活发电机并产生电力。
然后将该电力转回网格以供家庭和企业使用。
风能的优点
清洁能源部门已将风能与未来的固体替代品。以下是风能的一些优势:
Wind Power is Cost-Effective for Consumers
风能是消费者比其他可用电力来源更便宜的替代品。
从风力成本之间利用电力每千瓦时0.02- $ 0.06美元。
风能不受价格不确定性的影响,因为没有任何问题/钻孔/钻孔/压裂。供应是恒定的。这意味着即使在全球市场因天然气或石油成本而增加时,风能的电力价格也将保持不变。
风力产生新的工作
The wind sector employed more than2016年10万名工人in the United States alone.
能源部的风能技术办公室报告,风能部门将支持2050年600,000个工作岗位。This means that in the span of 34 years, the wind energy sector will have created 500,000 new jobs.
Wind Power is Clean
风能不会污染空气。与发电厂不同,燃烧化石燃料,将不健康的化学物质放入我们的空气中,风力涡轮机产生零大气排放。
With no atmospheric emission, we can reduce incidences of acid rain, greenhouse gases that deplete ozone, smog in cities, and human health issues from breathing unhealthy air.
风力是国内
通过减少对外国化石燃料的依赖,我们降低了对全球波动的依赖。
This means that when war erupts in Saudi Arabia and supply lines are interrupted, the United States will not be forced to pay higher prices or be limited by supply.
风力是可持续的
由于行星的不均匀加热,风吹。如果您考虑过,风权实际上是一种形式太阳能。
只要太阳存在并且地球旋转,就可以利用风力作为一种能量形式。
风能的挑战
与所有新的努力一样,利用风电并非没有挑战。以下是行业必须跨越的几个障碍:
风力有很高的初始投资
建造风电场和将这些风电场连接到网格的成本是投资。
The infrastructure already exists for fossil-fueled generators, but not for wind energy. This makes the initial start-up cost of wind energy much higher.
Wind Power Is Rural
建造风电场的最佳场所远非城市,其中大型建筑物块或中断空气流量。
这意味着大多数风电场都需要建在远程位置,并且必须安装传输线,以将电力带到远处城市。
由于城市是大多数企业的家园,就像这项服务,这消耗了该国的大部分电力,可能会导致问题源于远离电力消耗的电力来源。
风力需要土地
Large swaths of land must be devoted to wind energy in order to build wind farms.
对于一些土地所有者,风电场不是土地最有利可图的使用。私人土地所有者可以通过使用其他用途来转动更高的利润。这限制了风电场可用的土地数量。
风力可以影响当地社区
Local communities may not want wind farms built near them for aesthetic reasons. Communities may also fear noise pollution caused by wind turbines, or an impact on local wildlife.
The wind energy sector will have to work to overcome these negative perceptions.
风力涡轮机的真相:他们的能量of the Future
Like in all industries, it is a cost-benefit analysis that informs our decisions. Whatever negative perceptions or perceived inadequacies exist in the wind energy sector, they are heavily outweighed by the benefits of wind energy.
The debate about whether wind power is efficient should be put to rest.
Not only are turbines more efficient, but they are also cleaner, more reliable, more sustainable, and cause fewer human and wildlife health and safety issues.
The truth about wind turbines is that theyare未来的燃料。我们需要投资于我们的未来,并帮助拯救我们的星球,而是倡导风力和其他绿色能量。
