Thus the net extra specific energy needed compared to just raising the spacecraft into space is between 0 and .

Passive components can't introduce net energy into the circuit.

Once the supply of net energy stops growing, so does the global economy.

We should measure the net energy in your departure and destination environments.

With no net energy gained or lost from the now more humid air, sigma heat remains unchanged.

To create and build these structures consumes less net energy than comparable construction methods.

By the 1980s these increases were so large that using the concept for generating net energy seemed remote.

The store uses net zero energy for heating and cooling the interior.

Customers are paid their existing retail rate for any net energy they produce.

So as the domains get smaller, the net energy saved by splitting decreases.
