EVs are just cars with a bit less emissions and other externalities moved elsewhere on the planet.

Solar #photovoltaics and #wind power also have externalities that are largely ignored. They are not perfect.

Quite predictable #nuclearpower is absent in your comment.
To succesfully transition away from fossil fuels we also need nuclear.

We're more or less independent from the #power grid since mid March. 🔋

For example, a 2023 study [2] on Western United States found that #solar #photovoltaics (PV) "energy production decreases 8.3 % on average during high #smoke days at PV sites as compared to similar conditions without smoke present." [2]

However, #ClimateChange and human factors both contribute. This is because "#ClimateChange is increasing the #probability of ‘fire weather’" [1], but this increased #FireDangerByWeather acts on existing #ignitions, either natural or human-caused.

"Solar is King

… in the second quarter of 2023 alone, approximately 92 gigawatts (GW) of solar power were installed globally. Of that, 55%, or 51 GW, was installed in China. Quarterly global solar installations appear to be growing at 50% per annum over the past three years"

Photovoltaic prices are really low now, so if you've been thinking of investing in solar panels for your house, now is a good time!

You might be wondering, do solar panels work on cloudy days? Good question.

This article will answer all your questions and will help you understand how solar energy systems work in cloudy, humid weather. 👇

"In May, senators Jeff Merkley (D-Oregon) and Cory Booker (D-New Jersey) introduced the Pollinator Power Act. Its passage would direct the U.S. Secretary of Agriculture to prioritize solar projects funded by the Rural Energy for America Program that create habitat for pollinators underneath the panels. Pollinators such as bees, butterflies and beetles are responsible for pollinating three-quarters of flowering plants and 35 percent of food crops, but populations are in striking decline, in major part because of habitat loss."

@arndell repair and (re)use stuff beyond its designed lifetime. If I buy stuff I check if its possible to get spare parts for a reasonable price and if the device is repair-friendly and if its possible to get it cheaper in a broken state and save it from the landfill. A 10 year old laptop that can be repaired is fine for normal use. A 30 year old car that can easily be repaired with cheap parts I collectes from scrap yards is fine if I just drive a few 100 km per year (<20% of my cycling). Old solar modules are fine if they still create a bit of electricity, e.g. the ones in the attached pic are 50W Siemens ones that output 70W for both of them now. There are 18650 powerbank enclosures that can be filled with the cells from dead laptop batteries to store solar power to charge my phone...

Edit: sharing knowledge and helping others is another thing thats easily done. Today I meet someone to discuss #photovoltaics / #Steckersolar . Next monday is #repaircafe .

Solar energy plays a key role in the clean energy transition.

We welcome the #EUSolarStrategy and advocate for:
🌿 stronger emphasis on agricultural #photovoltaics;
🏭 solid support for the Solar PV Industry Alliance;
👩‍🏭 intensive promotion of training and skills development.

In #photovoltaics, photons knock electrons out of their bonds to generate electricity, and in #wind turbines, a magnetic field moved by, ...well, wind.

And the hyped #nuclearfusion, if it ever comes to scale? Brings a pot of water to a boil, again.
I'm a bit disappointed there. 🤷‍♂️

A few days ago my photovoltaic system on my roof was finally put into operation and after a few rainy days today is finally a day where the sun at least sometimes winks through the clouds.

I'm aware that #photovoltaics is only one building block on the way to sustainable energy production, but when I see live how much electricity is produced on my roof alone, it is extremely impressive.

@atthenius @anuckols @Lyle It occurs to me that a community garden is an interesting place to put sensors. They are secure. They are always locked when not staffed. Having even small amounts of electrical power enables use of sensing instruments AND fans for greenhouses AND shading of crops and volunteers AND maybe powering irrigation systems.

Representation of core-shell lanthanide doped #nanoparticles for #upconversion (UCNPs) capped with oleic acid.
UCNPs can absorb two or more low energy #photons and convert them into one photon with higher energy, which is then emitted. As-prepared UCNPs are usually capped with hydrophobic oleic acid to prevent aggregation with other nanoparticles and to control their growth.
They are of particular interest for bio-imaging, bio-sensing and nanomedicine, but also for photovoltaic applications.
