Zero Emissions: Natural Gas About to Compete with Wind and Solar

A new way to use natural gas could cut its carbon dioxide output to zero, making it competitive with solar or wind farms.

First Solar: Building Largest Thin-Film PV Plant

First Solar’s utility-scale PV plant has now been quietly up and running, in Blythe, California, for its first full month. Once it got a go-ahead in the summer this project only took three months to build.

Rooftop Solar Out Growing Utility Scale

Private solar installations are really taking off nationwide. In just two years, (about the same length of time it takes to get a pair of 250 MW solar power plants approved in California, for example), homeowners and businesses have added that much power to the Californian grid, just from individual rooftops throughout the state.

Wind Turbines: Calculating Cost Per Killowatt Hour

When I read about the training workshops for small wind power dealers for WePower, I found no information on the site to let you know how much their units will cost. But if you want to sell (or buy) their vertical axis revolving wind turbines, you’d want to know how cost-effective they are.

Off-Shore Renewable Energy Super Grid

This month Europe’s first electricity super-grid dedicated to renewable energy will become a political reality, as part of Europe’s plan to meet its target to reduce greenhouse gas emissions 20% below 1990 levels by 2020.

Nine countries will draw up formal plans to link up a super-grid of powerful clean energy projects strung out all around the North Sea in order to ship renewable power to the mainland.

$240 Million Wind Farm Completed in 4 Months

A North Dakota rural electric cooperative made history on New Year’s Eve, in completing the nation’s largest wind project to be entirely owned by a consumer cooperative.

The $240 million, 115.5 MW wind farm was begun in August and completed a mere four months later; three and a half hours before midnight on the last night of 2009. GE supplied the 77 1.5 MW turbines.

New Carbon Footprint Calculation

Norwegian scientists have created a new method of calculating carbon footprint that allocates the carbon produced in the country of consumption, not just in the country of production, bringing up some interesting issues and possible solutions to the difficulties of combating climate change.
