Let’s End Gas Subsidies

For some strange reason countries like Canada keep giving tax money to ultra wealthy oil and gas companies even though they keep killing all life on the planet. Let’s stop this. The team at Solar Share hosted a good information session on how we can reduce government money going to oil and gas, and of course, channeling that money to renewables. It’s worth a watch.

On February 12, over 30 participants joined us for our webinar about ending gas subsidies in Ontario, featuring Kent Elson (Elson Advocacy) and Jessica Hamilton (former political candidate and staffer).

We discussed the Ford government’s plan to overrule the Ontario Energy Board’s decision on gas subsidies, what “natural” methane gas is, and how to effectively engage with our elected representatives in Ontario.

There were some excellent questions and comments, and you can watch the recording here!

Wind Turbines & Birds, Ok; Gas & Birds, Not Ok

People opposed to a clean economy argue that birds get killed by wind turbines so therefore we shouldn’t build wind farms. Of course, those same people would argue that we should stick to planet-killing fossil fuels instead; somehow, in their minds using fossil fuels is better than renewables when it comes to protecting nature. To hopefully put this ridiculous debate to bed The Economist has stepped in. The magazine that is trapped in the last century agrees that when it comes to power generation and protecting nature that renewable energy is best.

But Dr Katovich did not confine his analysis to wind power alone. He also examined oil-and-gas extraction. Like wind power, this has boomed in America over the past couple of decades, with the rise of shale gas produced by hydraulic fracturing, or fracking, of rocks. Production rose from 37m cubic metres in 2007 to 740m cubic metres in 2020.

Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon. When drilling happened in places designated by the National Audubon Society as “important bird areas”, bird numbers instead dropped by 25%. Such places are typically migration hubs, feeding grounds or breeding locations.

Hawaiian Battery Better Than Coal

Hawaii just became an even better place to live thanks to cleaner air. The state recently decommissioned their coal power plant and replaced it with a much nicer looking battery complex. The battery system had to be designed with potential disasters in mind due to the risks of earthquakes, volcanoes, and more. Despite the local challenges the battery system is working effectively and if Hawaii can replace coal with batteries than all the other states can do it too.

Hawaiian Electric’s modeling suggests it can reduce curtailment of renewables by an estimated 69% for the first five years thanks to Kapolei Energy Storage, allowing surplus clean electricity that would otherwise go to waste to get onto the grid.

The utility also requested ?“black-start capability.” If a disaster, like a cyclone or earthquake, knocks out the grid completely, Hawaiian Electric needs a power source to restart it. The Kapolei batteries are programmed to hold some energy in reserve for that purpose. Plus Power located the project near a substation connected to three other power plants so the battery ?“can be AAA to jump-start those other plants,” Keefe said.

How Heat Pumps Work

Despite the climate crisis some places (like Canada) are still building houses with fossil fuel based heating systems, and this needs to change. Gas companies and their planet-killing kin have used regulatory capture to ensure their desire to change the climate continues. However, their best efforts to force customers to use dead dino juice people are turning away from old style furnace for new high tech heat pumps.

Heat pumps sound like magic since they somehow extract heat from cold winter air. Thankfully, the Guardian has put together a nice visualization of how heat pumps work. The gif above is not from their english language site.

Whereas gas boilers burn gas to produce heat, heat pumps do something more complicated. Sometimes described as working like a “fridge in reverse”, they use a mixture of evaporation and condensation to transfer heat from outside to inside a building. In a cold winter, it can be hard to understand how these devices work.

Solar Retaining Wall Goes Live in Switzerland

It might seem odd to put solar panels on the side of walls in a region with mountains, but that’s exactly what’s happening in Switzerland. One of the cantons in the country is looking to be powered by at least 40% renewables by 2035 (which is quite achievable); with terrain being scarce it’s hard to place large solar installations. However, retaining walls in some areas get a lot of sunlight depending on their orientations (south facing would generate more for example) and with geography like Switzerland’s there are a lot of retaining walls. The cantons of Appenzell Ausserhoden’s first installation generations 325kW which is the equivalent of 52 Swiss households.

The PV system was anchored on and in the masonry using an adhesive technique. An anchoring depth of a maximum of 90 mm could not be exceeded so that the retaining wall would not be adversely affected.

Due to the close proximity to the asphalt, the solar panels’ components are subject to exceptional corrosion requirements and are anodized for protection. Indirect components are made of aluminum – only the screw anchors are made of stainless steel.
