Michigan utilities met the state's standard this year, generating 10 percent of their electricity from renewable sources. Now, to reduce carbon emissions, some people in the state want to see the bar raised to 20 percent or higher, but paying for it remains controversial.
“What we found is that doubling our RPS would add about $1.70 per month for a typical consumer,” says Jeremiah Johnson, a professor at the School of Natural Resources at the University of Michigan.
UM set to open driverless-car test site Mcity on Monday
The University of Michigan will officially open its new testing site for connected and driverless cars on Monday. The 32-acre testing grounds, called Mcity, are designed to simulate urban and suburban roads with a network of controlled intersections, traffic signals, streetlights, sidewalks, construction obstacles and more, the university said in a release. The $6.5 million test track is operated by UM’s Mobility Transformation Center.
Three new kinds of battery that just might change the world (feat. Battery Lab Manager Greg Less)
So, it’s time to ask again: Why aren’t we all driving around in oxygen-powered cars? Well, the chemical reaction that produces energy in these batteries also happens to come with a considerable drawback. As it interacts with the oxygen, the aluminum degrades over time. It’s a type of battery called a “primary” cell, which means current only flows one way, from the anode to the cathode. That means they can’t be recharged. Instead, the batteries have to be swapped out and recycled after running down.
Renewable Portfolio Standards- the percentage of a given energy portfolio made up of renewable power sources- are a contentious issue in many states. In this blog entry, University of Michigan researcher Jeremiah Johnson describes his new study, which will describe in detail the various costs and benefits of adding more renewables to Michigan’s energy mix.
