What we need to do to stop global warming

Obviously, we need to stop the human enhanced extra greenhouse effect. There are a number of ways to approach this. Let me say right away that taking CO2, the main greenhouse gas of concern long term, out of the atmosphere is NOT one of the ways. Here’s why: It takes energy to put Carbon into…

By important, I mean people who have their hands on the levers of power, more or less, in areas that affect energy policy. I don’t really care if Uncle Bob doesn’t accept climate change. Uncle Bob votes for right wing yahoos anyway, that wasn’t going to change. Why should it matter what Uncle Bob thinks?…

A lot of higher education institutions are old, and back in the day, things were different. Not only were most schools simultaneously on top of and on the bottom of great snow covered hills, but they were often surrounded by nearly medieval settlement, or at least, pre-industrial ones, that lacked things like central heat, electricity,…

Barack Obama, Justin Trudeau and Enrique Peña Nieto, have made a joint announcement. As reported by NPR: President Obama and his counterparts from Canada and Mexico are preparing to unveil an ambitious new goal for generating carbon-free power when they meet this week in Ottawa. The three leaders are expected to set a target for…

Governments, and the people, should be filing law suits against the energy industry for causing the imminent collapse of civilization as we know it. But instead, the opposite is happening. From Reuters: TransCanada formally seeks NAFTA damages in Keystone XL rejection TransCanada Corp is formally requesting arbitration over U.S. President Barack Obama’s rejection of the…

This is bad news and good news, but mostly good news. No matter what you think of nuclear energy (and I’m one of those people who give it a stern look and remain suspicious), it does tend to produce electricity with the addition of much less fossil carbon into the atmosphere than, say, burning coal.…

Harvesting clean energy in cities

There is a new technology that can convert both solar and wind energy into electricity in such a way that it is suitable for use on urban rooftops. Here’s the abstract from the paper describing this work: To realize the sustainable energy supply in a smart city, it is essential to maximize energy scavenging from…

We often hope, even assume, that technology will fix our problems. We also know that sometimes technology creates a problem. In this case, technology can help us fix the problem of needing to keep the fossil carbon in the ground by making use of the sun, but created the problem of vaporizing birds with intensely…

The big complaint people have about renewable energy, or at least, the big complaint that has some merit, is that renewables, such as wind and solar, are intermittent and to varying degrees, unpredictably intermittent. This makes it hard to match demand for electricity to supply. Some aspects of this argument are overstated. For example, a…

Men and women are different, on average, in a number of ways. It all probably starts with who has the physiology to have babies and who doesn’t, and the differences spread out from there, affecting both the body and the mind. Decades of research show us that many of the body differences (but not all)…
