Hydro generation can balance wind energy and help solve the problem of wind power intermittency. Though, according to a report from the IEA’s Wind Task 24, Europe’s hydro generation has not been developed with balancing services in mind. Close to 50% of Europe’s hydro storage capacity is in Norway, which has 84 TWh of hydro […]
Wind Is The Cheapest Power Source in Uruguay
Wind Is The Cheapest Power Source in Uruguay. Uruguay’s state utility UTE is purchasing wind-generated electricity at less than half the price per MW hour that it pays for power generated from fossil fuels. The average winning price in a recent Uruguayan auction for three 50MW wind power projects was US $63.70 per MWh. The cost […]
Scottish Marine Energy Moving Forward
Leading engineering companies and commercial banks are putting money in marine energy projects off the coast of Scotland. The Scottish government believes the industry will be competitive with other renewable energy sources by the mid-2020s. Scottish Marine Energy Developing Tidal and wave energy technologies will make an important contribution to Scotland’s goal of generating the […]
The Cheapest Route to Germany’s Renewable Energy Goal
The EU Emissions Trading Scheme (ETS) is the cheapest route to Germany’s renewable energy goal, says Professor Colin Vance of the Rheinish-Westfälisches Institut für Wirtschaftsforschung (RWI-Essen). Most other renewable energy promotion policies are redundant. Germany should ditch its massively expensive feed-in tariff scheme, he believes. Germany faces a major challenge if it is to achieve its […]
Pakistan Looks to Wind Power in a Crisis
Pakistan’s national electric power regulatory authority has proposed a feed-in tariff for wind power projects of 14.66 US cents per kWh to run for 20 years. The tariff will be limited to projects of 5MW to 250MW that achieve financial close before the end of 2012. A tariff of almost 15 US cents is one […]
Photovoltaics – the Law of Comparative Advantage in Action
China has an important share in world patents for upstream high-value processes in photovoltaic cell manufacture, such as the production of silicon, ingots and wafer segments. But those patenting activities are the result of Chinese public research institutes’ efforts to break the country’s dependence on foreign suppliers of hi-tech components, according to researchers from Mines Paris Tech. That R&D is not […]
Design Race in Wind Turbine Drivetrains
This article was first published on Leonardo Energy on 10th January 2011 The silhouettes of three-rotor offshore wind turbines on the horizon is familiar to millions of people in coastal regions around the world. But there is no universal design for the drivetrains within the wind turbines’ streamlined nacelles that sit on top of the turbine towers. […]
Indian Budget 2011-12: Renewables Battle to Keep Pace
This article was first published on Leonardo Energy on 16th May 2011 With India’s $1 trillion-plus economy achieving GDP growth of 8.5% in 2011, expected to increase to 9% in 2012, the Indian Government is unable to grow its energy infrastructure fast enough to meet demand. An extra 70 GW of power was planned between 2008 […]
Global PV market up 139% Tougher times ahead
This article was first published on Leonardo Energy on 5th September 2011 A record 18.2 GW of solar photovoltaics was installed across the world in 2010, according to the annual survey from the Californian solar energy consultancy Solarbuzz. That is growth of 139% in installations over 2009. The survey reports that the PV industry generated US $82 billion […]
