Modern ocean power systems look to convert the mechanical energy of waves or tidal movement to electrical energy. But that’s not all the sea has to offer. It may also be possible to capture and convert the enormous quantities of heat produced by magma escaping through seafloor vents—an undersea version of geothermal energy.
It is rare indeed to witness, at an otherwise staid industry forum, the public rebuke of the country’s most prominent supplier to the electric power industry. But at the Keynote session and Power Industry CEO Roundtable of the 2008 ELECTRIC POWER Conference & Exhibition in Baltimore this May, Milton Lee, general manager and CEO of […]

I believe there are three basic objectives for the energy industry in the modern era. First, to provide a reliable and ample supply. Second, to ensure that the supply is provided at the least cost to consumers. And third, to accomplish the first and second objectives with the least possible adverse effects on the environment. […]
By Steven F. Greenwald and Jeffrey P. Gray These should be good times for environmentalists who focus on “green” energy policy. More than half the U.S. states have adopted renewable portfolio standards (RPS) that require utilities to meet specific renewable generation targets, and many are considering additional actions to reduce greenhouse gas (GHG) emissions. Such […]
Ethanol and biodiesel have become mainstream fuels that are increasingly used in combination with gasoline or petroleum diesel in automobiles. Now these same versatile fuels are starting to be used to power gas turbines. LPP Combustion LLC has developed a fuel preparation and delivery system that converts liquid fuels such as No. 2 fuel oil, biodiesel, ethanol, and coal liquids into substitute natural gas, which existing natural gas hardware can burn while enjoying reduced emission rates similar to those of natural gas.
The idea of harnessing the vast power of Earth’s oceans has tantalized humans for more than a century. Today, the prospect of generating as much as 4,000 TW of clean energy from marine sources is fueling a resurgence of interest in a variety of technologies.
