A Heat Pump Water Heater Is The Energy Saving Equivalent Of 7 Solar Panels & Costs ⅙ the Price

Posted by in categories: solar power, sustainability

My sister is in the process of building a house in Ohio, and I’ve been having conversations with her about how to make it green. She and my brother-in-law both consider me to be eco-crazed (arguably rightly so given the climactic and political stakes) and so tend to raise eyebrows when I make one of my many helpful suggestions.

For example, I suggested they install a central heat pump instead of inefficient electric resistance heating, but only after consulting their HVAC guy, who is a fan of heat pumps, did they decide to install one (Woo-hoo! They’ll save thousands of dollars and pounds of CO2 with that choice). They are also making their home solar-ready and plan to install panels in the next couple of years — this is mostly because solar offers a sense of self-reliance that is perennially popular across political and geographic boundaries.

However, when I tried to talk them into installing a heat pump water heater, I ran into serious resistance. If you haven’t heard about heat pump water heaters, they are an enormously powerful energy/CO2 reduction technology lying hidden in plain sight in the most humble of appliances — the water heater.

Solar panels that can generate electricity at night have been developed at Stanford

Posted by in categories: solar power, sustainability

While standard solar panels can provide electricity during the day, this device can be a “continuous renewable power source” during the day and at night.

Solar panels created from crop waste produce energy even if the sun isn’t shining

Posted by in categories: engineering, particle physics, solar power, sustainability

The British James Dyson Foundation presented the first Sustainability Award to Carvey Ehren Maigue, an electrical engineering student in the Philippines. He was awarded for creating new material from recycled crop waste that has the ability to transform ultraviolet (UV) rays from the sun into electrical energy. The technology could soon be turning the windows and walls of buildings into a rich new source of electricity.

The invention of the Filipino university student is called AuREUS (Aurora Renewable Energy and UV Sequestration). Both AuREUS devices (Borealis Solar Window and Astralis Solar Wall) use the same technology used in the beautiful Northern and Southern lights. High energy particles are absorbed by luminescent particles that re-emit them as visible light. A similar type of luminescent particles (derivable from certain fruits and vegetables) were suspended in a resin substrate and is used as the core technology on both devices.

Could ‘hot carrier’ solar cells break the theoretical efficiency limit?

Posted by in categories: solar power, sustainability

Up to 50% of the energy absorbed by a solar cell is lost as heat. Scientists are now developing a third generation of “hot carrier” solar cells that take advantage of this heat, potentially breaking the Shockley-Queisser limit of silicon-based PV.

Taiwan’s New Solar Panel ‘Sun Rock’ Will Deliver 1 Million kWh Per Year

Posted by in categories: government, solar power, sustainability

Get in, we’re going to the threshold. Solar power is undoubtfully one of the most preferred renewable energy sources of the day. As the need for energy rises with the improving technology and the rising population, companies try to come up with the most efficient solutions that promise to meet the energy demand of the world.


Taiwan’s forthcoming Sun Rock could supply excess energy to the power grid

Taiwan’s government-owned power company, called Taipower, commissioned Sun Rock, with plans to use it as a visitor facility, in addition to a storage and maintenance center for renewable energy devices. But the most obvious and impressive feature of the forthcoming project is the facade, which will be almost totally smothered in solar panels (don’t worry, there will also be vents and windows to promote the natural exchange of light and air). But 1 million kWh is a lot — the U.S. government has found that an average household uses roughly 11,000 kWh annually, which will rise (because of course it will) before the Sun Rock is finished.

Wind and solar energy amounted to 10% of the global energy consumption in 2021

Posted by in categories: biotech/medical, climatology, economics, solar power, sustainability

There’s still a long way to go, but it’s an important milestone.


Ten years ago, solar and wind didn’t even make up 1% of our global energy mix. Now, in just a decade, they’ve reached 10%. It may not seem like much, but becoming such a significant part of the global energy mix in such a short time is remarkable — though there’s still a long way to go.

The past couple of years have been horrendous in more ways than one, but that doesn’t mean all is bad in the world. In fact, renewable energy continued its impressive growth, according to research from Ember, a climate and energy think tank.

IAAC students design Solar Greenhouse for food and energy production

Posted by in categories: food, solar power, sustainability

It is intended to be scalable and adaptable to a variety of settings, such as on the rooftops of inner-city buildings. The aim was to design and build a system that could be replicated in both rural areas and on roofs of urban building spaces.

The 130-square-foot structure is constructed from Aleppo Pine (Pinus halepensis) that was milled, dried, processed, and pressed into laminated wooden elements on-site at Valldaura. The glass roof, carefully arranged in a heliomorphic ‘diamond’ shape, allows for full solar capture both by the plants inside and the semi-transparent solar panels integrated within the glass to power the entire structure. The greenhouse only uses about 50% of the energy it produces, leaving the other half for the nearby Valldura Labs facility.

The solar-powered greenhouse also features a fully functional nutrient delivery system consisting of storage tanks, nutrient inflows, tubing to feed the plants directly, and a matrix of LED strip lights to facilitate longer growth cycles. The ground floor will be used for germinating the seedlings that will be planted in the gardens, while the upper level will generate a sizable harvest using advanced hydroponic techniques. All planting beds will use a sawdust substrate, a former waste product of the Green Fab Lab at Valldaura put to imaginative reuse.

Max Laughlin and his controversial theory: CERN sent us to a parallel universe?

Posted by in categories: cosmology, solar power, sustainability

The young man has made several statements that compromise the scientific community, but the most shocking is related to CERN and how it could have destroyed our universe.

Regarded as a genius child and listed as the “most intelligent young man in the world”, Max Laughlin surprised the world with his great intellectual abilities.

With only 13 years old he could develop from scratch its own device for energy access. A system that is capable of providing all the necessary energy without the need for oil, coal or solar energy.

Scientists Achieve Record Energy Efficiency for Thin Solar Panels

Posted by in categories: chemistry, solar power, sustainability

Scientists from the University of Surrey and Imperial College London have achieved an increase in energy absorption in ultra-thin solar panels by 25%, a record for panels of this size.

The team, which collaborated with AMOLF in Amsterdam, used solar panels just one micrometer thick with a disordered honeycomb layer on top of the silicon panel. The biophilic design draws inspiration from butterfly wings and bird eyes to absorb sunlight from every possible angle, making the panels more efficient.

The research led to a 25% increase in levels of energy absorption by the panels, making these solar panels more efficient than other one-micrometer-thick panels. They published their findings in the American Chemical Society’s journal, Photonics.
