Small scale wind energy – theme for July 2013

Small-wind-and-solar-CornwaSmall scale wind energy has all those renewable energy advantages – no greenhouse gas emissions, free fuel, easy and quick to install, and direct electricity supplied. Small wind energy involves fewer regulations in installation, than large turbines. It works particularly well in conjunction with solar panels

Small-scale wind power is the name given to wind generation systems with the capacity to produce up to 50 kW of electrical power.  Wind turbines have been used for household electricity generation in conjunction with battery storage over many decades in remote areas.

Off-grid system users can either adapt to intermittent power or use batteries, photovoltaic or diesel systems to supplement the wind turbine. Equipment such as parking meters, traffic warning signs, street lighting, or wireless Internet gateways may be powered by a small wind turbine, possibly combined with a photovoltaic system, that charges a small battery replacing the need for a connection to the power grid.

Grid-connected domestic wind turbines may use grid energy storage. and where feed-in tariff is available, sell excess power to the utility company.

Like solar power, small scale wind energy can be used in city or country. Also, like solar power, it has special advantages for remote areas.

It makes me laugh, when the nuclear lobby starts touting the idea of “small modular nuclear reactors (SMRs)”. Just like solar panels, small wind generators are already in use, in many parts of the world. (But these mythical SMRs would have to be ordered in great quantities, by some national buyer, before they would even risk making the things.) Meanwhile wind and solar are quickly set up, leave no radioactive wastes, require no special security. And of course – the killer factor – they’re cheaper.

  1. Actually, you are mistaken about wind and solar leaving no radioactive waste. They both use Rare Earth Elements, and REEs are basically always accompanied with thorium and sometimes uranium. It turns out that wind, per unit energy provided, produces about 8 times the weight of radioactive waste than a Liquid Fluoride Thorium Reactor would.

    Just thought you should know.

  2. I am totaly in favour of wind power, But the image you put forward are prime exmples of everything that is wrong with small wind power.You have displaed a selection of expensive wind chimes. Min distance for install of wind turbine is 20 times the the hight of th nearest obstruction,
