@rgauder Hey good for you. Impressive. I have a jackery battery pack with two solar panels - works well in summer.

Hey Dan, it took a while, but finally just had solar installed on the roof as the numbers finally worked. We took control of our electricity bill, helped the grid out and reduced our carbon footprint. We can add more in the future once we get an EV. (Still waiting on a practical affordable solution.) I do like the fact that we’ll soon have no electricity bill:)

If you're at #CNA2025 this week, stop by booth 323/325 and learn how Ontario Tech is Canada's Nuclear Training Ground!

CNA2025. Ontario Tech shines.

Unfortunate that Canada does not have a city in the top 50. economist.com/graphic-detail…

Ontario’s carbon intensity keeps rising.

Useful chart from the Globe and Mail. While Americans are wealthier on average, average Canadians are wealthier (see what I did there ...) when one looks at median wealth.

The Mauna Loa Observatory in Hawaii has recorded the biggest annual jump in atmospheric CO2 levels since measurements started there in 1958. #Echobox=1737811150" target="_blank" rel="nofollow noopener">newscientist.com/article/246440…

@elonmusk So too pollution and dangerous waste.

Success is uncertain, but entertainment is guaranteed! ✨

Wow Ontario has low carbon electricity in the middle of the night.

A hot day with higher demand in Ontario. Little wind and solar (and some nuclear offline) so unfortunately we are stuck with burning gas, and breaching the low-carbon limit of 100g.

On the longest day of the year - showing Canada's warming climate stripes. We and the world warmer than anytime over the last 125,000 years and increasing quickly.

The bright side of hope. economist.com/leaders/2024/0…

Arguing a very bright future. economist.com/interactive/es…

As Ontario gets hotter and AC increases, much higher demands for electricity (and more gas increases our carbon emissions). Heat pumps would help (as well as lower emissions in winter).

Register quick! June 10th is the last day to get in
