Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. Their report on the device — 1,000 times thinner than a sheet of paper — appears in the journal Nano Letters.

Alberta phased out its coal-fired electricity in record time representing the largest single action to reduce greenhouse gas emissions in Canada. The trouble is a lot of the coal was replaced by natural gas which produces 60% of the emissions of coal. Can the fossil fuel-infatuated province also capitalize on its amazing renewable energy resources …

Alberta's last coal-fired power plant stopped burning coal on June 16, 2024 at 10:57 pm. The coal phase-out was originally proposed for 2061, but in 2015 a new target was set for 2030. On June 16 the last lump of coal was burned to produce electricity six years ahead of schedule. The phase-out represents the largest reduction in greenhouse gas emis…

EAVOR has pioneered a new kind of geothermal that can provide heat and power almost anywhere on the planet. This could be the missing link in the energy revolution that could not only help electricity get to net-zero. It also helps solve the even bigger challenge of how to heat buildings with zero emissions.We talk to Jeanine Vany of EAVOR, a compa…

PART 2 - Summerside PEI had no electricity generation capacity a decade ago and then did some amazing things. First (in part 1) they added wind power, a smart grid and energy storing furnaces. Then they added AI-powered solar microgrids and a solar and battery farm right in the City. The little City with no generation capacity has achieved 62% loca…

PART 1 - Summerside like the province of PEI had no energy production except expensive backup diesel generators just a decade or so ago. Something had to change. So in an amazing transformation, they set up their own utility, built a wind farm in the city, installed a smart grid and thermal energy storing appliances and got to 42-46% renewable ener…

This sounds counterintuitive, but a new study has found Electric Vehicles (EVs) are driving the price of electricity down and increasing net profits for utilities. Thanks to time-of-use pricing EV owners are shifting their charging habits to non-peak times thus making much more efficient use of existing grid resources. GreenEnergyFutures.ca CKUA.co…

Heat pumps are the future of heating and cooling. We found them heating and cooling in net-zero homes, in water heaters and clothes dryers and now there are models rated to -35C. The reasons are quite simple: they are incredibly energy efficient, and since they run on electricity it's pretty easy to run them and produce few or no emissions.GreenEne…
