Reducing CO2 Emissions by Targeting the 5% of Power Plants

Electric energy production using non-renewable processes produces an immense amount of carbon, and as a civilization we can’t afford to put more carbon in the atmosphere. Researchers from the University of Colorado Boulder set out to figure out how much pollution do power plants actually produce and what can we do about the worst ones. They found that 73% of pollution came from just 5% of power plants, unsurprisingly those plants used coal. So let’s shut them down!

According to the authors of the research, the emission intensity of the ten worst plants exceeded those of other fossil fuel power plants in their home countries in 2018 at a rate 28.2 percent to 75.6 percent higher than their counterparts. This suggests that the plants are very inefficient in burning coal, the research showed.
“Why these relatively inefficient plants are used so heavily is a topic ripe for future investigation,” the authors wrote.

Given the IPCC Report, Let’s Ban Oil Propaganda

industry

Today the United Nations’ Intergovernmental Panel on Climate Change (IPCC) released data that proves the world has rapidly warmed 1.1 degrees Celsius higher than pre-industrial levels, and is now careening toward 1.5 degrees. They are calling it a red alert for the planet. Obviously this isn’t good news.

The oil industry along with the oil-consuming automobile companies spend billions every year telling us to spend more to kill the planet. This should stop. Over at the National Obseror they ask a very simple question: “are we letting fossil fuel companies sell us our own demise?” They propose an all out ban on adversting oil and gas consumption like we did with tabacco.

Advertising works. That’s why it’s a multibillion-dollar business, and it’s why oil, gas, car and airline companies spend as much as they do seeking our favour. According to one study, over a recent 30-year period, the world’s five biggest oil companies spent US$3.6 billion on ads specifically aimed at shoring up their reputation as green-friendly. Ads are one reason why gas-guzzling pickup trucks are so popular, even among those with no genuine need for them. As Quebec environmental group Équiterre found in a study released earlier this year, aggressive advertising helps to explain why light-duty vehicles — SUVs, pickups and vans — now account for 80 per cent of new vehicle sales in Canada, which in turn is a big reason greenhouse gas emissions from transportation are still rising. 

Because advertising matters so much to the fossil fuel corporations, it ought to matter to the rest of us, too

Want Better Communities? Get rid of Homeowners

The North American dream often hinges on owning the shelter you reside in, but with raising home prices this is a challenge for many. It may work out in the long run though as we should be creating systems that favour renters over owners since homeowners tend to hold back progress. Of course, we will need to protect renters from evictions and so on. Regardless, over at Vox they have an interesting analysis on home ownership which is worth considering:

Researcher Rachel Bogardus Drew points to more than a century’s worth of messages praising the benefits of homeownership, “everything from personal freedom and self-determination, social equality and inclusion, personal and economic success, and a better quality of life.”

One of the messages Drew cites is from a 1916 article in the Hutchinson News telling readers: “Owning a home raises one in the estimation of his neighbors and associates. … Nothing gives a man a better standing in a community than the fact that he is a house-holder, a payer of taxes on real estate.”

Converting to Co-Ops will Save Small Businesses

The pandemic clearly caused chaos in the business world from lockdowns to supply chain issues, and this has caused many small businesses to face closure. Small businesses closing isn’t good for local economies and there are solutions to support these small operations. The best option is to convert to a cooperative.

That’s right, in order to save capitalism we need less idolization of individuals and more focus on shared growth. Business can survive through distributed risk and recovery by converting to cooperatives.

Co-operatives offer stable business models that provide good jobs. They are often better than conventional businesses in terms of responding to and surviving crisesbecause they source capital locally rather than with distant shareholders, meet local community needs, and foster trust and mutual aid.

During economic downturns, for instance, co-op members will often amend wages and revenue distribution rather than lay off employees.

The overall lack of knowledge of the co-op model is not surprising. There is systemic bias against solidarity-based economic activity by mainstream economists and business pundits, and a related lack of co-op content in post-secondary business and economics courses.

A Cheap Material for Producing Power from Waste Heat

Machines produce a lot of waste heat, and if we can capture that heat we can convert it into electric energy. Capturing thermal energy is currently inefficient because of thermal dynamics and the lack of super capacitors. Not to be deterred by these obstacles, researchers have found ways to efficiently capture thermal energy. By using an inexpensive material a small thermoelectric can be placed to convert heat to power.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”
…
The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.
