Renewables

Nanomanufacturing technology works on the concept that materials reduced to the nano scale can show different and improved properties compared to those exhibited on a macroscale. For nanotech giant, Applied Materials, the ability to apply thin films at the atomic level is the answer to making solar energy more cost effective. Michael Splinter, chairman, CEO and president of Applied Materials, spoke with Fortnightly about nanotech developments for utility-scale solar.

Are renewables truly marking the start of a new economy, creating both economic growth and reliable jobs? Answering that question takes a complex analysis, but the numbers suggest green benefits might be smaller than expected.

The power grid has been slow to embrace renewable energy sources. In order to allow renewable energy sources to evolve into a solution rather than a headache, new tools and processes will need to be developed to forecast and control renewable production capabilities.

Six weeks ago, FERC opened a notice of inquiry to invite industry comments on whether wind, solar, and other intermittent energy sources face unfair obstacles in wholesale power markets. Now assigned their own acronym—VERs, for “variable energy resources”—renewables make up a growing percentage of the nation’s energy supply portfolio. But as FERC notes, they present “unique challenges,” especially in terms of constraints on location and limits on the degree to which system operators can control or dispatch individual VER units. Thus, FERC suggests that certain common rules and practices, such as those for unit commitment, dispatch, and scheduling, might make it overly difficult to integrate VERs into the grid.

The feds are ready to replace disjointed state policies with a coordinated national renewable energy credit market. Treating low-carbon energy consistently will promote investment in renewables.

Dramatic changes are coming to the electric industry, sparked by a surge of renewable energy and related transmission. Growth in demand-side resources, conservation and smart technologies will add integration dilemmas to an already complex power system.

23 million square miles of tropical oceans daily absorb solar radiation equal in heat content to about 250 billion barrels of oil. Ocean thermal energy conversion technologies convert this solar radiation into electrical power by exploiting the thermal gradient temperature differences between the surface and the depths. This enormous resource merits a closer look as policy makers consider alternative technologies for serving future energy demands.

The Province of Ontario, Canada is the first jurisdiction in North America to implement a European style feed-in tariff (FIT). It also was the first jurisdiction in North America to have a comprehensive standard-offer program for electricity supply from renewables.

Back in June, the Bismarck Tribune ran an interview with North Dakota Public Service Commissioner Tony Clark that showed just how difficult it is to build national consensus for renewable energy.

Renewable generation resources have become the rallying cry for policymakers and developers alike as the movement grows to generate electricity in a more climate-friendly manner. Pending federal legislation creating a carbon cap-and-trade market and a national renewable portfolio standard (RPS), together with existing state requirements, is spurring utilities that lack renewable generation to acquire some—no matter the federal legislative outcome—and causing utilities with sizeable renewable generation to expand their existing portfolios.
