If you start from scratch and design processes that do not need high temperatures, you can use solar energy to the full.

Cold-blooded creatures would need very even temperatures if their intelligence was not to switch on and off with variations in the weather.

The tadpoles continue to stay associated with the egg mass for several days, and continue to need higher temperatures to grow quickly.

This plant needs moderate temperatures, 60 to 75 degrees.

Here even the beds were heated for creatures who needed temperatures far beyond the heat comfortable for men.

There are also some seeds that need warmer temperatures to trigger sprouting.

"They need high humidity and warm temperatures and that's what we've got."

Some seeds need warmer temperatures than others to germinate.

They need temperatures of 70 - 95 degrees F. and high humidity in their environment (between 60%-90%).

Many methods to grow the semiconductors need high temperatures, but a cheaper approach would be to make them in solution.
