A rare story about electricity tariffs in Africa. One Kenya Shilling (KES) is 0.014 US$.

British Gas launched what it calls Britain's "greenest" available energy tariff today. It will cost gas and electricity customers on average £84 per year more than the firm's standard dual fuel deal. The launch reflects high customer demand which is pushing green energy tariffs into the mainstream, according to British Gas. Energy regulator Ofgem last month put forward plans for a star-rating system to help customers understand the array of green tariffs on offer.

Powering the Green Economy The Feed-in Tariff Handbook By Miguel Mendonça, David Jacobs and Benjamin Sovacool 'This insightful book explains how to implement the most effective policy to get onto a path towards renewable energy.' Dr David Suzuki, scientist, environmentalist and broadcaster

"A Japanese trade ministry panel today proposed expanding the feed-in tariff to require utilities to buy electricity at a premium from hydropower stations, wind turbine and geothermal operators. Utilities may have to buy renewable power at between 15 yen (17 cents) and 20 yen a kilowatt hour, according to a report released in Tokyo today. The incentive program would run for between 10 and 20 years, it said. The government wants to supply 10 percent of the country's primary energy from renewable sources by 2020, compared with about 3 percent in 2007, according to the International Energy Agency. The proposed tariff compares with 5 to 7 yen a kilowatt hour utilities pay for nuclear power and about 8 yen for oil- fired generation, said Tomohiro Jikihara, an analyst at Deutsche Securities Inc. in Tokyo.

This merits revisiting. With the recent collapse of the Spanish market, the correction of the German market and the expected collapse of the French PV market, FITs prove unsustainable or victim of their own success. Once the market picks up, governments can no longer support their price tab. Moreover, they are based on a false premise: the cost of taking a technology through the learning cycle is prohibitive - it requires too many tens of billions.

The topic is complex. Some underlying questions: * Why promotion of renewables was set-up? * What is the complete economic balance of renewables promotion? (expenses in subsidies, but savings in fuel imports, job creation, exports.... some interesting studies have been done on this - see for instance Macroeconomic study on the impact of Wind Energy in Spain - http://www.aeeolica.es/userfiles/file/aee-publica/091211-executive-summary-2009.pdf) * Is the allocation of subsidies cost done correctly? Electricity consumers often pay extra-cost, but benefits go to other pockets. Should there be a cost re-allocation to make the model sustainable? * Is regulatory framework evolving less rapidly than technology? FITs on PV in 2008 could be significantly reduced compared to FITs in 2007, and so on. How to accomodate regulation to that quick cost reduction? * Had governments defined a cap in global subsidies amount? Not really, this explains why they are all reacting to initial plans. * Development of technology and market drives costs down. Why some few countries should make this investment to the benefit of the entire world? * Have we excessively promoted market growth and neglected technology development? Are we paying too much for building power plants with primitive technology?

@Fernando - I agree that the topic is complex. However, I'd refrain from making claims on employment effects. This is an area where secondary effects are rarely taken into account. While I realise these claims are popular, basically nobody knows.

According to the Energy Saving Trust, the new tariffs are expected to provide a rate of return of between 4.5% and 8% for a typical well sited 4kW domestic installation.  - is this right? Research by DECC has shown that solar PV uptake is highest...

While other governments are reducing their feed-in schemes, UK is moving towards them.

The measures introduced by Energy Minister Eamon Ryan yesterday include a guaranteed feed-in tariff of 19 cents per kilowatt hour of electricity for the first 4000 microgeneration installations over the next three years.

"Paying Home Gen customers 15p for every unit of electricity they generate is groundbreaking," said Juliet Davenport, CEO and founder of Good Energy. "It sets the benchmark for a UK feed‐in tariff and signals the importance of rewarding total generation, not just exported electricity."

To support the necessary growth and expansion of offshore wind in order to meet the EU's 20% renewables target, several barriers need to be overcome. Low feed-in tariffs for offshore, limited and costly grid connections and complex authorisation procedures are seen as key obstacles by the offshore industry, delegates heard at the second day of the European Offshore Wind Energy Conference in Berlin.

The world largest thin-film rooftop photovoltaic power plant was connected to the grid Wednesday after four months of construction. Over 37,000 First Solar thin-film modules have been installed on the 90,000 sqm large rooftop of a logistic centre in Ramstein, Germany. Three inverters convert the continuous current into alternating current. Under the supervision of COLEXON up to 40 mechanics and electricians were working at the construction site. Thorsten Preugschas, board member of RPSE AG, is proud of the success:" With this landmark project we were able to confirm our strong position as a project developer, demonstrating high product and service quality, a quick implementation and excellent price-performance ratio for our costumers." The solar power plant will produce about 2.4 million kWh per year. Based on a feed-in tariff of 46.3 cent/kWh the installation will earn over 1.1 Mio Euro per year. This also accounts for saving of 2 tonnes of CO2 emissions per year.
