Like a wet blanket swollen with water, the climate can only absorb so much excess heat before global temperatures begin to rise.

Blinds have been installed to remove the need for air conditioning, keeping it cool during the day and allowing excess heat to filter out at night.

BBC: Does Shard point to design's future?

One town in the United Kingdom has a rather unique idea: to heat the public swimming pool and sports complex with the excess heat from the crematorium next door.

The power density of processor chips used in PCs today is on a par with that inside a nuclear reactor--and anyone who's ever perched a notebook computer on his lap for a prolonged period knows all that power often manifests itself in excess heat.

Some power operators fear, however, that that they will get sued if they equip their facilities so that they could capture excess heat, which could alter the generation process and thus violate the New Source Review, writes Melissa Mullarkey, for Recycled Energy Development.

FORBES: Recycling Wasted Heat and Power Could Clear the Air

Gamers do not have to worry about excess heat while having all of their settings cranked up, keeping the laptop cool is accomplished by an efficient and quiet design using a larger, single omni-directional blower fan and dual heat pipe and heat sink system, minimizing the noise and increasing the efficiency over other designs that utilize two smaller and louder blowers.

When they eventually pair up with others, they dump their excess energy and thus heat the junction a little.

ECONOMIST: Microrefrigeration

He said well-designed systems can operate effectively in the UK, delivering in excess of three units of heat for every unit of electricity used to pump the heat in and around the property.

BBC: Heat pumps 'need tighter regulations'

Rather than letting the heat escape, a cogeneration plant uses the excess energy to power a heating and cooling system.
