🔗 The United States has its first large offshore wind farm, with more to come
America's first commercial-scale offshore wind farm is officially open, a long-awaited moment that helps pave the way for a succession of large wind farms.
Fantastic news. We can’t install wind and solar fast enough. -
🔗 Why did renewables become so cheap so fast?
Fossil fuels dominate the global power supply because until very recently electricity from fossil fuels was the cheapest. This has changed dramatically. In most places power from new renewables is now cheaper than new fossil fuels.
Fascinating read. -
🔗 Frugal computing: On the need for low-carbon and sustainable computing and the path towards zero-carbon computing
On the need for low-carbon and sustainable computing and the path towards zero-carbon computing.
Computing and infrastructure currently use around 11% of the world's electricity and is projected to grow 3 - 4 times over the next 20 years. As makers of software (and hardware) we've got to find a way to extend the lifespan of devices for as long as possible.Taking into account the carbon cost of both operation and production, computing would be responsible for 10 GtCO₂e by 2040, almost half of the acceptable CO₂ emissions budget
The report about the cost of planned obsolescence by the European Environmental Bureau [7] makes the scale of the problem very clear. For laptops and similar computers, manufacturing, distribution and disposal account for 52% of their Global Warming Potential (i.e. the amount of CO₂-equivalent emissions caused). For mobile phones, this is 72%. The report calculates that the lifetime of these devices should be at least 25 years to limit their Global Warming Potential.
25-years on the same mobile phone. I can't even imagine. I'd love it if that were possible in today's world. Maybe if it was a "dumb" phone. But even then wireless network's lifespans aren't even that long these days.
I used my iPhone 6S+ for around 4 years until a pin broke on it and I could no longer charge it. "Repairing" it (my first option) would have meant getting a new iPhone 6S+ for half the cost of a brand new iPhone XR. I hope I can keep my phone for at least as long as I've had my current computer (7 - 8 years).
