I got home last night from a couple of days in San Francisco at the InterSolar show, an event whose purpose is to promote the numerous technologies that surround humankind’s efforts to power our planet from our local star.  And …

Ironically, of all the renewable energy investment opportunities I like, the one that’s attracting the most interest over the last week or so is my collection of 20-or-so run-of-river hydrokinetics projects in Brazil—despite the World Cup.  Apparently, the whole country’s …

The movie “DamNation” is screening tonight at a local church.  Though I haven’t seen it, I know enough about it to summarize it as follows: Damming up our nation’s rivers has come at a vast environmental cost, and it’s time …

“DamNation” Examines the Legitimacy of Hydro-Electric Dams Read More »

My major concern about the viability of marine hydrokinetics (MHK) is that there is very little attention paid to the levelized cost of energy that it represents.  Is there a real trajectory for getting it in line with other forms …

Attendees at the Energy Ocean show in Atlantic City, NJ last week received a snapshot of some of the latest technology for extracting the energy from moving ocean water, and a glimpse into how all this is improving year-to-year.  This …

Here’s another post from the Energy Ocean show in Atlantic City, NJ.  As I mentioned earlier, ocean energy in its various forms, including off-shore wind, tidal, ocean current, wave, and OTEC, lacks the maturity of its cousins in renewable energy, e.g., …

Just a quick note to let readers know that this Energy Ocean show is really worth-while, and I’m very glad I built an extra day onto my trip to New York to attend it.  The introductory speaker opened the proceedings …

Here’s an article in the Wall Street Journal that presents a short summary of different types of devices that generate electricity by converting the kinetic energy from ocean waves. I was a WSJ subscriber for many years when I was …

Here’s a thinly guised attempt to ridicule the idea of government subsidies for renewable energy generally, clothed in a report on a failed company with a huge device to extract energy from ocean waves.  Obviously, the burden of proof of …

Ocean Wave Energy Machines Have More Potential Than Some Would Like To Admit Read More »

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 …
