Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source—such as the distance from a power plant to street lamps on a remote highway—a lot of energy is lost during transmission.
在美国,照明约占总耗电量的7%。由于照明通常远离电源——例如从发电厂到偏远公路上的路灯——因此大量的能源在传输过程中会损失掉。
Connect Intake-tube with intake-tube of air filter of the rewinder, then get through entering power source.
将进气管与复卷机空气过滤器的进气管相连,然后进入电源。
I would like nuclear fusion to become a practical power source.
我期望聚变可以成为实用的能源。
They have a material that supplies electrons and a power source that lifts the energy level of those electrons.

Similarly, divination. Divination is an attempt to discern the future that, once again, heads right to the source of power.
类似的还有占卜术,占卜是一种试图看清未来的法术,它的终极目标,也是神力的源头。
And so Richard is learning a grammar of race even while he tries to work out how to use language as a source of power in his family.
