Introduction
在我们的日常生活中我们做许多工作。我们许多人通过体育活动。一些工作用的工具和其他设备。但他们也需要能量。有许多类型的能源如电能、机械能、热能、光能和风能。在我们的日常生活中,我们从电池获得电能。电也是从核电站,水电站、风电场,阳光。鳗鱼发电。他们使用这种能量来保护自己免受敌人。风扇、灯、电视、洗衣机和冰箱都需要电。源发电称为能源。

电子的运动物体引起的力量。这种能量被称为电能。产生的能量做功循环电流的电路。这种能量被称为电能。电能转化成许多能源形式。例如,电极,放大器、电磁铁、灯泡、和化学变化。电能被储存在电池和电容器。我们使用电能运行各种设备和化学能做饭或运行的车辆。一切都是可以从一个源。我们需要知道如何选择所需的能源可用的形式获取能量。一种能源必须每单位质量可以做更多的工作,容易,易于储存,最重要的是它是负担得起的。下面给出电力能源。
Thermal Power Plants
每天都在大量化石燃料燃烧热发电厂发电和加热水。它被称为火力发电厂电能使用热能生成。它是更容易传输电能比长距离运输煤炭或石油。所以,热电厂煤或油田附近安装。

太阳档案高温通过集中其射线做饭。太阳能电池覆盖着玻璃盘子。这是通过使用太阳能电池将太阳能转换为电能。太阳能电池的主要优势是,他们没有移动部件,需要很少的维护。大量的太阳能电池的结构称为连接太阳能电池板,为实际应用提供电力。
Tidal Energy
Wave energy is harnessed by constructing a dam with a narrow opening on the beach. A turbine installed at the dam’s opening converts the tidal energy into electrical energy. Kinetic energy can be obtained in the same way from offshore wind that produces electrical energy. Waves are created by strong winds blowing across the ocean. Only where the waves are strongest is the wave energy at a different rate. Various types of devices have been developed and used to harvest wave energy for turbine rotation and power generation.
