Better Solar Helps Bitter Hops

Agrivoltaic setups aren’t new to regular readers of this site as we’ve seen many times that certain crops benefit from the shade solar panels provide; and, the solar panels benefit the farmers by producing clean energy. Now we know that hops, which flavour beer, thrive under solar panels. A German experiment with a special solar setup for hops has proven more successful than expected since the hops fared better against disease.

Which crops thrive under solar panels depends on many factors, and for a crop like hops a default solar field setup is not a good one. Hops like to grow straight up which means that the solar panels need to be elevated high off the ground. The hops then grow up to the solar panels and get lots of benefit from the cooling effects of the panels themselves.

The pilot project — a collaboration between Wimmer and local solar technology company Hallertauer Handelshaus — was set up in the fall of last year. The electricity made at this farm can power around 250 households, and the hops get shade they’ll need more often as climate change turbocharges summer heat.

Solar panels atop crops has been gaining traction in recent years as incentives and demand for clean energy skyrocket. Researchers look into making the best use of agricultural land, and farmers seek ways to shield their crops from blistering heat, keep in moisture and potentially increase yields. The team in Germany says its effort is the first agrivoltaic project that’s solely focused on hops, but projects have sprouted around the world in several countries for a variety of grains, fruits and vegetables.

Putting Names on the Climate Crisis

- Adam Clare 1 Comment

The people who make decisions to continue us on a path of climate catastrophe have names and addresses. We need to shame people who are actively engage in profiteering off of killing every living thing on the planet, and that’s exactly what Environmental Defence has started to do. They have created a list of the Canada’s climate villains – those in positions of power that delay climate action and/or encouraging more environmental destruction. The good news about this is that Canadians who care about the climate are upping their game to call out those that are profiting from our demise. The more climate action we take the better – we only have one planet so let’s not burn it down!

Canada’s Oil and Gas industry has long been the biggest barrier to climate action. Despite the harmful impacts that people in Canada and around the world are suffering daily from the warming climate and lack of action, the oil and gas industry continues to spew pollution and rake in record profits and receive billions in government subsidies. We are done taking the blame as individuals. The time to expose the true climate villains is now!

It’s Simple to Install Solar Panels

- Adam Clare

Efficient of solar panels continues to increase and the costs of installing them keep going down, meaning that there’s never been a better time than now to install solar panels. One of the great things about solar is how scalable it is, you can install a small system on a townhouse to a massive system on fields of land. It all comes down to budget. If you’re in Canada you can make use of the Canada Greener Homes program to get up to $5,000 towards the cost of your solar panels. The faster people move to renewable energy sources the better the chance we have at averting climate catastrophe.

What solar capacity do you need, or can you afford?

The average home in Ontario uses 8,250 kWh of electricity annually (this average will increase over time as buildings are electrified); roughly 10 kW of solar energy capacity would be required to meet that demand. Most homes will be able to fit somewhere between 5 kW and 10 kW so you’ll need to assess your own roof. SolarShare’s Operations & Maintenance Coordinator, Bob Ross, estimates that when accounting for building permits, fees and solar panels, a 5 kW system will cost approximately $18,000, and 10 kW around $28,000. Check out this calculator to estimate your potential savings from installing solar panels.

Coal Continues Collapse

One of the worst ways to generate electricity is to burn coal to heat water to spin turbines, the only reason this power generation exists is due to the cheap cost of coal. OF course, when coal is brunt it releases radiation and carbon into the atmosphere worsening local areas and the planet. Thankfully the use of coal is decreasing in totality around the world. This past year the USA produced more power from renewable sources than coal, which is a step in the right direction. Ideally the nation will ge their coal use to zero.

According to the Energy Information Administration, a federal statistical agency, combined wind and solar generation increased from 12 percent of national power production in 2021 to 14 percent in 2022. Hydropower, biomass, and geothermal added another 7 percent — for a total share of 21 percent renewables last year. The figure narrowly exceeded coal’s 20 percent share of electricity generation, which fell from 23 percent in 2021.

The growth in renewable electricity was largely driven by a surge in added wind and solar capacity, the agency said. Texas was the top wind-generating state last year, producing more than a quarter of all U.S. wind generation. It was also the leading state for natural gas and coal power. Iowa and Oklahoma landed at second and third in wind generation, accounting for 10 percent and 9 percent of national wind power respectively.

How Neighbourhoods Are Fighting Climate Change

- Adam Clare

Neighbourhoods in Canada are trying to change the world by focussing on their own street. Across the country there are streets of houses proving that a transition from using fossil fuels to heat and power a home is possible in a country that loves to subsidize the oil and gas industry. And yes, going green saves money too.

The Pocket Change Project provides not only an example of how to convert your neighbourhood but information on how to do it. It may seem like a daunting task to go for fully electric in a place that guzzles gas for homes, but it’s doable and with the guides from Pocket Change it’s easy.

If you’re fortunate enough to own a home then you should you do your part and cut out gas.

When it comes to reducing household emissions, Dowsett is clear-eyed about where he thinks the responsibility lies.

“We who are the affluent ones are the ones who create an outsized carbon problem; people who are less affluent do not,” he said. “I think it’s very disingenuous of us to try and impose austerity on people who are not the problem. We are the problem. We need to change,” he said, before adding with a laugh, “rant over.”

Other Pocket residents echo this sentiment. “I believe that people who are privileged enough have a responsibility to do this,” said Lori Zucchiatti O’Neill. “A lot of people can’t afford to do this, but we can afford to do this. So it’s like, full steam ahead.”
