The World Energy Council estimates that nearly two thirds of all primary energy is lost before it is converted to useful energy.

We believe that nuclear energy, when produced in accordance with safety and environmental procedures, can be a useful way of meeting the increasing energy demand worldwide.

It comes in on the side the useful stuff is the dark gray, and the un useful stuff, which is called the rejected energy the waste, goes up to the top.

But we've got an opportunity to recycle them into something more useful that enables us to get energy all of the time.

These figures are indicative of the associated energy and development problems only, since access to electricity in itself is not a very useful target unless the associated use of the energy is also documented.

The polarization property of microwaves was very useful in differentiating objects on the ground, as surfaces reflect differently depending on the polarization of the incident energy.

Owing mainly to its environmentally negative externalities, an unregulated energy market is not a useful governing mechanism, because it is unable to internalize the environmental costs. It has been calculated that the most contaminating energy sources would have to pay a 70 tax to reflect their negative externalities.
