This #Amazon is the opposite of the homonymous rainforest: 1,200-acre stretch of farmland transformed into 7 Amazon data centers each larger than a football stadium to support #AI expansion.

High #energy and #water consumption impacting the environment and local resources. These data centers use #naturalgas which is not a #renewable energy source.

A reminder that AI is not abstract, it has a footprint and #environmental cost.

A Better Way to Get Around in the Amazon: Solar-Powered Canoes

A growing fleet of electric boats ferries Indigenous people through the heart of the Ecuadorean Amazon, providing a cheaper and greener alternative to gas-powered vessels.

Some 42.5% of net electricity generated in the European Union came from #renewable sources in the first quarter of 2025, a 4.3-percentage-point decline on the corresponding period a year earlier (46.8%). ⚡

For people into #photovoltaics, do you ever consider dropping an inverter and going full DC?

The century old debate between Edison and Tesla might need a revision, because of the mode of energy production. We shift to a local production now and the main advantage of AC - ease of long range transfer - becomes irrelevant. And now we have easily accessible DC-to-DC electronic impulse converters so it's not even hard to serve a large range of devices.

Most of the devices we use are DC-powered anyway. Just drop the power supply and plug it directly to the wall socket. There could be a set of standard sockets - round for 10V, elipse for 12V, flower for 24V, triangle for 30V, square for 40V and pentagon for 50V. And ofc. USB for 5V because that's already a standard. So that you can't physically make a mistake.

Every single LED bulb has a tiny power supply in the lightbulb. That's why they break. It's not the diode, it's the PS. It's often very low quality. The diodes are fine.

It's an interesting thing to consider.

I checked on the status of my solar system this morning, given it's an overcast day.

I found the battery was full already at 09:30!

My system saw the weather forecast and charged up the battery from cheap grid energy during the night, to ensure we weren't beholden to any price spikes during the day.
