This is an older take, but I think it goes well with today's environmental issue. And two cyclists on the road who are also environmentally friendly
A team of experts from the University of Exeter have shown that mimicking the v-shaped posture adopted by Cabbage Whites to heat up their flight muscles before take-off, can raise the amount of solar power by nearly 50 per cent.
The secret appears to be the angle that the butterflies hold their wings, approximately 17 degrees from horizontal. It could even improve the effectiveness of sunbathing.
Cabbage White butterflies are known to take flight before other butterflies on cloudy days – which limit how quickly the insects can use the energy from the sun to heat their flight muscles.
This ability is thought to be due to the v-shaped posturing, known as reflectance basking, they adopt to maximise the concentration of solar energy, which allows for flight.
On Saturday morning there was a strong frost and freezing fog to begin with, but once the sun was up and its heat began to penetrate the forest, the frost on the tree trunks and forest floor began to melt and evaporate. The scene was quite magical.
in a world in need of peace...filled with fighting for natural resources...then Humanity as a family realizes the many natural resources of greatest abundance...but also protects our Earth...and the life of future generations to be born...

Solar energy - Énergie solaire
"To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science."
Albert Einstein
This is a project launched for Bristol's year as European Green Capital. So far I have shown you the Fog Bridge, the Boats in the Woods and now a tree made of solar panels. It's all happening here!
The Energy Tree is a community-led, public art installation and renewable power source designed to engage the public in energy issues. Volunteers from the Bristol Drugs Project, who completed a programme with project-lead Demand Energy Equality, built the solar panel 'leaves' for the tree from scratch and worked with Bristol-based artist John Packer on the metal sculptural work for the tree's structure. It'll also provide free on-the-go phone charging and WIFI.
It is situated in Millennium Square, right next to the Planetarium which makes a great background for this futuristic piece of art!
The Crescent Dunes Solar Energy Project is a concentrating solar power (CSP) plant built near Tonopah in Nye County, Nevada. The 110MW plant is the first commercial-grade solar power plant in the U.S. to be fully integrated with energy storage technology. It is also the world’s largest solar power facility with storage. The estimated cost of the project was $1B. In September 2011, Tonopah Solar Energy received a loan guarantee from the US Department of Energy (DOE) to finance the construction of the Crescent Dunes solar power plant. The remaining project cost was financed by SolarReserve, the Spanish engineering and construction company ACS Cobra, and the Spanish banking firm Santander. The project entered its commissioning phase in February 2014 following completion of the construction phase. It was expected to generate about half a million megawatt-hours annually of emission-free electricity, enough to meet the needs of approximately 75,000 households. It officially began commercial operations in September 2015. At this time, the project was under contract with Nevada Energy, the electric utility for most of Nevada, to supply its entire output. Perhaps unsurprisingly for such a large facility using cutting-edge technology, however, the plant was plagued with operational difficulties, mostly plumbing issues in handling the extremely hot & corrosive molten salt. Nevada Energy canceled the contract for non-performance in 2019, & the corporate owners filed for bankruptcy. Under new owners, the plant re-began production again in 2021, however, it remains to be seen whether the difficulties were solved.
Solar power has a lot of promise, but a fundamental challenge: it works only when the sun is shining. Hence, any solar power system that can supply energy 24/7 requires some means of energy storage. Electricity, however, is notoriously hard to store, especially at power plant scales. This challenge drives the need for alternative energy-storage technologies. Crescent Dunes has a novel approach to the electricity storage problem. Rather than boil water directly, solar heating is used to melt a salt reservoir, and the molten salt then boils water via a heat exchanger. The cooled but still-liquid salt is then returned to the reservoir for reheating. The hot-salt reservoir is large enough that it can continue boiling water to generate power for 10 hours, long enough to smooth out production when the sun is not shining. Over 10,000 mirrors are focused, under computer control, onto a tower some 656 feet high, where pipes carry the molten salt to be heated. The salt exits to a reservoir where it is held around 1,050 degrees Fahrenheit. When electricity is to be generated, this salt is run through the heat exchanger, which makes superheated steam that turns a turbine.

two of three solar "power towers" at the 400 megawatt ivanpah solar plant located on the california/nevada border. a field of computer-contolled mirrors reflect and focus sunlight on a boiler which glows white hot. steam from the boiler is used to spin a turbine, generating electricity.
the air around the tower is superheated by the concentrated "solar flux" to a temperature in excess of 1000 degrees farenheit. birds that fly thru this zone are instantly incinerated, becoming "streamers" of smoke. some ecologists have estimated the annual avian mortality upwards of 25,000 migratory birds a year.
