Big Week for Solar CSP: Two Plants Leap Ahead

Nevada’s Crescent Dunes CSP project enters “commissioning phase” while California’s Ivanpah plant is to be officially dedicated.     From Renewable Energy World James Montgomery, February 12, 2014 It’s a utility-scale concentrating solar (CSP) two-fer this week: Crescent Dunes kicks off its commissioning process, while Ivanpah’s official dedication follows a month of on-again/off-again ramping. Today…

Study: In the EU, Rooftop Solar to Become Cheaper Than Coal

Cost predicted to decline steadily for wind and solar.       From RenewEconomy Giles Parkinson, January 28, 2014 A new study suggests that wind and solar plants are already competing economically with fossil fuel in Europe. Soon, even household rooftop solar PV systems will generate electricity more cheaply than coal. The study from Germany’s…

Concentrated Solar Power: Focusing the Sun

In the race to harness renewable energy, one technology combines a new-age focus on solar energy with the relatively old concept of steam-driven power plants. Known as Concentrated Solar Power (CSP), these systems rely on arrays of mirrors to focus the sun’s heat on a “working fluid,” which creates steam to drive a turbine. As…

Renewables and Resilience

An article published in the New York Times on Monday brought to light an interesting paradox that’s plagued many homeowners who have invested in solar power. When we see homes with solar panels on their roofs, we often think of them as “off the grid”, dependent on their own power generation and thus immune to…

Harnessing Solar Energy

The sun showers Earth with an unfathomable amount of energy every minute. In fact, more solar energy hits our planet in one hour than the entire global population consumes in a year. Of course, this statistic is outrageous because the vast majority of the sun’s energy is impossible to harness without covering the planet in…
