Climate: urgent action required Climate: urgent action required

It's been another busy period for GWEC's Steve Sawyer, who has attended an eye-watering number of international events on the circuit. Here, he brings us up to date with a view from the front line of the climate change debate…

Round 3 of UK offshore wind development underway Round 3 of UK offshore wind development underway

96 entities have set their sights on the UK's latest round of offshore wind project development.

Renewables and carbon trading

Where next for renewable energies in the fast-developing world of carbon trading?

Clean energy stocks take a hit

During the months of August and September 2008, the WilderHill New Energy Global Innovation Index – which tracks 88 of the top clean energy companies – fell 26.8. This represented the biggest two-monthly fall in the index's history, and took it to a level 50% below its peak in November 2007. So what does the future hold?

Focus on Anaerobic Digestion Focus on Anaerobic Digestion

Energy from Waste (EfW) is increasingly being seen as something of a silver bullet solution to enable less organic waste to be sent to landfill, as well as deliver cleaner energy. George Marsh looks at a technology that is revolutionising the possibilities for organic waste – Anaerobic Digestion

Tidal power: an update Tidal power: an update

Compared to wind and solar, tidal power is still regarded as a renewable energy technology that remains unviable on a large scale. But throw together climate change, political will in the UK and the US, entrepreneurial enthusiasm and academic research - with some significant investment - and a new mood of optimism is starting to pervade the sector.

Private PV installation a sign of things to come in sunny Alberta Private PV installation a sign of things to come in sunny Alberta

Better known internationally for its mountain parks and vast tracts of oil sands, Alberta may also soon emerge as the most progressive province for solar development in Canada – a country lagging in development of this technology.

Focus on small hydro Focus on small hydro

For centuries civilisations have taken advantage of the power of water. Once used by the Greeks for grinding wheat into flour, the water wheels of the past have been transformed into highly-efficient turbines that generate electricity. Renewable Energy Focus takes an in-depth look at the current renaissance in Small Hydropower in the EU.

Biomass in the USA

Will the USA be able to count on large amounts of biomass energy in the next few decades? Some reports and organizations are more bullish than others, discovers Lyn Corum.

Case study: biogas harvest for US farm Case study: biogas harvest for US farm

Farmers around the world are showing increased interest in Anaerobic Digesters, as a result of higher energy and fertiliser prices, the growing costs of complying with waste disposal legislation in many countries and the continuing need to diversify in order to maintain farm incomes. One dairy farm in the USA is using the technology to produce electricity, heat and bedding for animals.

Making wind more efficient? Making wind more efficient?

With rising demand for wind power, wind turbine manufacturers are searching for solutions to make their turbines more efficient, at the same time increasing reliability and reducing maintenance. Renewable Energy Focus' Kari Larsen investigates two routes for achieving this: integrated drivetrains and direct drive technology.

Innovation in Concentrating Thermal Solar Power (CSP) Innovation in Concentrating Thermal Solar Power (CSP)

In this review of concentrating solar power (CSP) developments, Robert Palgrave looks at how technology is being developed to provide a more complete lower cost offering to the electricity market, and how the future for CSP includes not just power generation, but also the production of gas and liquid fuels.

EU PVSEC: a review of 2008's solar PV event

For those that missed the photovoltaic (PV) industry's biggest event of the year in Valencia, Spain, Paula Mints offers a review of the event's major talking points…
