extract the suns heat.
if you put thermal heaters on your roof, to extract heat and heat up your water, are you not taking the heat out of the atmosphere? if every home on the planet had thermal heaters on their rooves, would that not extract heat from the atmosphere and save us a ton of energy at the same time?
you can't stop global climate change. it is changing all the time. what we MUST do is stop poisoning this eden in space. we're crapping on our own doorsteps!
imo home batteries invalidate nuclear energy and with wind turbines and photovoltaic panels and even exercise bikes (seriously!) to top up the battery, along with a low-priority grid trickle charging during low-use periods, we can harvest the clean and free energy that is all around us.
most noise and pollution in cities is due to the infernal combustion engine, so when we all start driving electric cars we can enjoy a cleaner and quieter life with less people getting and asthma from this toxic crap!
worry about TOXICITY not TEMPERATURE.
