Renewable Tech – ocean power part 2

by Richard Perkins

This is the sixth article in a continuing series on renewable energy technology. Today we’ll continue our discussion of ocean power. As previously mentioned, the term covers virtually any device that extracts power from the sea. That’s a broad range of technologies, including wave and tidal energy conversion systems or the more exotic concepts of [...]

Renewable Tech – ocean power part 1

by Richard Perkins

In this fifth article in my continuing series on renewable energy technology, I’d like to talk about ocean power. The term covers virtually any technology that extracts power from the sea, ranging from fairly well-known wave energy and tidal energy conversion systems to more experimental ideas like ocean thermal energy conversion (OTEC) and salinity gradient [...]

Renewable Tech – geothermal power

by Richard Perkins

This is the fourth article in my continuing series on renewable energy technology, which I published previously here on Associated Content. Today I’ll be talking about geothermal energy. Like wind and hydropower, most geothermal systems are electromechanical in nature: they generate electricity by spinning loops of conductive wire in the presence of a strong magnetic [...]

Renewable Tech – solar PV

by Richard Perkins

In my previous posts in this series, I described hydropower and wind power. Both of these renewable technologies could be classified as electromechanical systems. They convert the mechanical energy of falling water or moving air into electrical energy through the principle of electromagnetic induction. Today, I’d like to introduce a technology of an entirely different [...]

Renewable Tech: wind power

by Richard Perkins

In my first post in this series, I talked about hydropower, specifically hydroelectricity. I mentioned that hydropower was one of the oldest forms of renewable energy, but wind power is arguably older. People have been using wind power to propel ships (yes this counts as wind power) for over 5000 years. There are historical references [...]

Renewable Tech: hydropower

by Richard Perkins

I’ve decided to start my primer on renewable power technology with one of the oldest forms of renewable energy: hydropower. Water wheels have been used for centuries to run mills, providing mechanical power directly to heavy machinery through rotating shafts. The leap from mechanical power to hydroelectricity was a small one, once the relationship between [...]

Stand and face the tide

by Richard Perkins

The renewable energy market in the Bay area continues to be an active one. Unfortunately I have found the latest “surge” in interest in renewables to have uncanny similarities with another infamous and ongoing surge. Those who want to take credit are quick to claim that the surge is working! Those who are in the [...]
