Here’s a renewable energy concept that I’ve been seeing here and there over the past decade. It’s a means by which a city can generate clean electricity from the water flowing under streets through pipes.

High-Altitude Wind
The subject of high-altitude wind isn’t new.
Run-of-River Hydrokinetics
It’s sad to see that run-of-river hydro hasn’t taken off, since it’s such an elegant way to extract the kinetic energy from moving water; such an approach has very little impact to aquatic life, and raises few other environmental concerns.
Concept in Ocean Wave Energy
Here’s a video depicting one of variations on the theme of extracting energy from ocean waves. Though I’ve seen countless numbers, I haven’t studied each of the variants thoroughly, so it’s only a guess when I say that this seems …
The Cost of Utility Scale Solar and Batteries Coming Into Parity with Natural Gas Peaker Plants
In the wake of a recent and fairly significant blackout in Southern Australia, grid operators made two immediate investments, both focused on meeting future peak electricity demands: an 250 MW open-cycle natural gas plant and a 100-megawatt/129-megawatt-hour battery from Tesla, …
Renewable Energy Products that Cause Embarrassment To the Industry
One of the challenges facing solar and wind energy is capacity factor, i.e. the ratio of the total energy generated by a device to the total energy that it’s potentially capable of generating (multiplied by 100, to make a percentage). …

The Solutions Project
My long-time colleague Lindsay Oliver writes, Hi Craig; Have you seen this (The Solutions Project) yet? This is more than interesting: Yes, Mark Z. Jacobson (professor at Stanford) is a legend to us renewable energy people.
Interesting Approach to Hydrokinetics
A reader asked for my comment on this technology: turbines installed inside of municipal water pipes that converts some of that hydrokinetic energy into electricity. First, let’s start with the most obvious: this doesn’t apply to water that is flowing …
Dozens of Ideas in Ocean Wave Energy
I just reviewed another in a long series of attempts at ocean wave energy. This one is similar to a Pelamis, but, because it requires less material it will be less expensive, thus offering a lower levelized cost of energy …
Investors Jumping Into Wind Energy With Both Feet – Here’s Why
Readers who may be wondering about the cost-competitiveness of renewable energy will be interested in this piece on the levelized cost of energy (LCOE) associated with wind. Hint #1: It’s very good news, and it provides real hope that wind, …
