Interesting stats on EVs and energy use in the US, developments in wind and tidal power, a plastic recycling microfactory, and an "unprecedented collapse" in EU fossil fuel generation.
Heata is a company based in the UK that reuses waste heat from cloud computing to heat water in people’s homes. Customers get a server set up in their home that connects via their Wi-Fi to a decentralized network of servers in other people’s homes, all of which are processing data from companies that pay Heata for its cloud computing services.
According to this MIT Technology review article, each server prevents one ton of carbon dioxide per year from being emitted and saves homeowners an average of £250 (USD$420) a year on their hot water bill.
I’ve read stories about capturing the waste heat from data centers and otherindustries to use for other purposes but I think this is the first company I’ve seen that installs servers within people’s residential homes to heat their water. Sounds like a great idea and once again illustrates how much valuable "stuff" we humans create – whether it's materials or energy – that we are just throwing away into the environment when we could be making much better use of it.
The IEA-OES has released a roadmap on how the world's leading nations can develop 300 GW of ocean energy by 2050 – creating 680,000 jobs and removing over 500 million tonnes of carbon emissions in the process.
