How solar is transforming an old mining town
You hike over the crest of the hill and there it is: 96 sun-tracking solar masts, each with 42 solar modules — 4,032 modules in all — perched on the side of a hill with the beautiful Rocky Mountains in the background. It’s called the SunMine project and it’s all part of the reinvention of Kimberley, B.C., from mining town to a clean tech, tourism town of the future. ...

Tracker Bankability: The Truth Behind the Reports
A major reason The Big Short was such a widely acclaimed book and movie was because it was able to take the complicated financial arcana that led to the housing crisis and make it understandable and entertaining. During the lead up to the crisis, there was a tremendous amount of money to be made originating very questionable home loans, bundling them into portfolios, and then selling these ...

Bright future of solar lighting
Hybrid solar powered lighting (HSL) isn't anything like solar light based power that changes over daylight into power. Through the utilization of optical strands, HSL catches daylight, diverting it and funneling daylight into a building. At the point when there is practically no daylight, these installations use power with the goal that consistent lighting is accomplished. Gatherer units, ...

Concentrating Solar Power Global Outlook 09 - Why renewable energy is hot
What is CSP? CSP (Concentrating Solar Power) systems produce heat or electricity using hundreds of mirrors to concentrate the sun’s rays to a temperature typically between 400 and 1000ºC. There are a variety of mirror shapes, sun-tracking methods and ways to provide useful energy, but they all work under the same principle. Individual CSP plants are now typically between 50 and 280MW in size, ...
