actually it is insanely simple.

- there is no infinite exponential growth in a finite environment

-without the biosphere intact there is no human life

- every system that uses up its non -#renewable resources, depletes its renewable resources faster than the rate of replenishment, or pollutes its sinks faster than the rate of breakdown of pollution

WILL #COLLAPSE.
basic #systems #ecology.

but keep on #infighting over fractions of degrees you guys.

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.

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.

#solar and #battery installation at a relatives house did well for #resilience - a cable break cut off the #UKPN grid feed for around an hour - whole house remained with #power from the #renewable #energy sources, the battery reserve was barely touched due to good sunlight (the people in the house didn't even need to switch off high consumption equipment, although I had suggested this should the power cut have lasted any longer (the grid supply returned around an hour later) #electricity

#Renewable power reversing #China’s #emissions growth
China has been installing #renewableenergy at a spectacular rate, and now has more renewable capacity than the next 13 countries combined, and four times that of its closest competitor, the US.
It's the country's first one-year emissions decline that's not linked to economic issues. The latest shift, however, was driven largely by the country's #energy sector, which saw a 2% decline in emissions over the past year.

If you're interested in learning how you can more deeply participate in or support our mission of building community sovereignty and stewarding abused land, you can find options for in-person or financial participation on our website:

rancholibertad.com/participate

We just opened our Supporter tier, and look forward to offering more opportunities to support locally and from afar in August. Those who subscribe at the Supporter tier receive a twice yearly gift basket of goodies from the Ranch (the first will be sent in December) as well as access to participate in quarterly Q&A posts.

You will also know (perhaps most importantly) that you are tangibly supporting projects that enable us to better serve residents (now and in the future), guests seeking sanctuary, and the land. Projects such as tree planting, renewable energy infrastructure, sustainable building, animal stewardship, sustainable and place-sensible food production, and more.

We are so grateful to you for your interest and collaboration ✨

“Several days on, the cause of #Europe’s biggest #blackout in two decades is still being investigated. Spain’s grid operator, #RedEléctrica, says a loss of generation in the country’s south-west led to a sudden cascade of failures.

What tripped off, why, and how this escalated so dramatically is unclear.

But the fact that an entire peninsula could be plunged into #darkness in a matter of seconds has caused alarm around the world, raising urgent questions about the stability of #EnergyUInfrastructure at a time when many countries are switching to low carbon #electricity instead of burning fossil fuels”

“Our power systems were conceived for an era of centralised, predictable generation,” says #XavierDaval, chair of France’s #renewable energy trade association #SOLERSER. “But the emerging electric world is #distributed, #digital, and #adaptive. This is not a glitch to patch — it’s a #paradigm that must be rethought.”

Spain’s grid operator Red Eléctrica has confirmed that renewable energy sources fully met electricity demand across the country’s peninsular system for the first time on April 16.

Wind generated 256 GWh, accounting for 45.8% of total output. Solar followed with 151 GWh, or 27%. Hydroelectric sources added 129 GWh, making up 23.1% of the mix. Solar thermal contributed 11 GWh, or 2%, while other renewables added another 11 GWh, or 1.9%. Renewable waste generated 1 GWh, or 0.2%.

pv magazine InternationalSpain hits first weekday of 100% renewable power on national gridSpain’s grid ran entirely on renewable energy for the first time on April 16, with wind, solar, and hydro meeting all peninsular electricity demand during a weekday. Five days later, solar set a new record, generating 20,120 MW of instantaneous power – covering 78.6% of demand and 61.5% of the grid mix.
