Iraq Looking to the Sun to Power its Future

- Adam Clare

Iraqi oil fields have a lot of fossil fuels ready to be exported, and that’s a problem. The Iraqi population, like many oil states, don’t benefit from the cheap oil that corporations extract and export. As a result Iraqis have now turned to solar power for their local energy needs. The current installation of solar panels is relatively small, but they are gaining in popularity and being a nation that gets a lot of sun we can only hope that more people see the light. Let’s keep oil in the ground and put up solar panels.

In nearby Sulaymaniyah, the second-largest city in northern Iraq’s autonomous Kurdish region, only 500 out of the 600,000 households are equipped with solar panels, said Sirwan Mahmud, a spokesman for the province’s electricity department.

Solar power had seen “rapid progression”, he said, after the region’s parliament adopted incentives in 2021 to compensate households for any excess electricity that they generate.

The region aims to build three commercial solar power plants with a total capacity of 75 megawatts (MW), he added.

Kenyan Farm Foments Fossil Free Fertilizer

- Adam Clare


Yes, fertilizers exist that don’t make use of fossil fuels; however, the use of petoreluaem based fertilizers have become a mainstay of modern industrial agriculture. This use of fossil fuels for fertilizer has led to the agriculture sector’s carbon footprint being as large as it is. The transportation of the fuel then as a fertilizer leads to large bills and emissions. Now, a farm in Kenya has started producing fertilizer using solar power. The process uses water to create hydrogen which then gets some nitrogen to form liquid ammonia, a key fertilizer.

Green ammonia, made from water using clean power, promises to curb the climate impact of fertilizer. If produced on site, it could have the added benefit of insulating growers from supply shocks.

“The average bag of fertilizer in sub-Saharan Africa travels 10,000 kilometers,” Talus founder Hiro Iwanaga told Bloomberg. With a small green ammonia plant, like the one coming online in Kenya, “you can locally produce a critical raw material, carbon free

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.

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.

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.”
