@Rainmaker1973 The power used by humans is so tiny compared to how much power from the Sun reaches Earth!
Solar power is ~1GW per sq km. At current solar efficiency, net electrical power is ~200 MW per square km.
The entire United States can be powered by a small corner of Texas.
@Rainmaker1973与太阳辐射到地球的能量相比，人类使用的能量是如此之小！
太阳能发电量约为每平方公里1GW。按照目前的太阳能效率，净电力约为每平方公里200兆瓦。
德克萨斯州的一个小角落可以为整个美国提供电力。
