Out riding the motorcycle and taking the long scenic way into work. This is the hydroelectric dam up the river from my house. If I wasn't off grid solar this is where my electricity would come from. But I like having the reliability of solar in case the storms knock out the transmission lines which always happens.

This energy may be green energy, but the trash burning electric plant a city away negates this so much. Yes that city burns trash. And has advertising on large billboards pretending it's a great thing. Not cool. And I can smell it.

"South Korea's HD Korea Shipbuilding & Offshore Engineering plans to develop a small modular reactor for use in shipping in cooperation with the UK's Core Power and the USA's Southern Company and TerraPower."

We know there are nuclear-powered submarines and aircraft carriers. How you you all feel about nuclear powered container ships?

"The shipping industry consumes some 350 million tonnes of fossil fuel annually and accounts for about 3% of total worldwide carbon emissions. In July last year, the shipping industry, via the International Maritime Organization, approved new targets for greenhouse gas emission reductions, aiming to reach net-zero emissions by or around 2050."

"There is no net-zero without nuclear."

"In January this year, a memorandum of understanding was signed between Lloyd's Register, Zodiac Maritime, Korea Shipbuilding & Offshore Engineering and Kepco Engineering & Construction for the development of nuclear-propelled ship designs, including bulk carriers and container ships."

"The reactor to be jointly developed centres around TerraPower's Molten Chloride Fast Reactor design. The technology uses molten chloride salt as both reactor coolant and fuel, allowing for so-called fast spectrum operation which the company says makes the fission reaction more efficient. It operates at higher temperatures than conventional reactors, generating electricity more efficiently, and also offers potential for process heat applications and thermal storage. An iteration of the Molten Chloride Fast Reactor -- known as the m-MSR -- intended for marine use is being developed by TerraPower."

Disused mine in Finland is being turned into a gravity battery to store renewable energy

The firm has developed an energy storage system that raises and lowers weights, offering what it says are “some of the best characteristics of lithium-ion batteries and pumped hydro storage”.

When there is excess power - from wind turbines on a windy day for example - weights would be winched up the Pyhäsalmi mine’s 530-metre auxiliary shaft. To generate energy, these weights can be released turning the winches into generators creating either a short burst of electricity or a slower trickle depending on what is needed.

The gravity energy system would be able to store 2MW of power and integrate into the local energy grid.

One of Europe’s deepest mines is being turned into a gravity battery

A Scottish company is using the Pyhäjärvi mine to build its first full-scale prototype gravity energy store.

With the growing concern across the province that the #Alberta #Energy Regulator seems to operate without sufficient public transparency and has vast discretionary powers, Alberta Wilderness Association opted to host a panel discussion on the theme "Reconsidering the Alberta Energy Regulator." The agency seems to be held captive by industry interests, rather than functioning as it is meant to: making decisions based on the best interests of Indigenous communities, the environment, and the public at large. Recent incidents, like the Kearl spills — and AER's response to it among others — highlights this point. #tarsands #oilsands #oil
