Today
Renewable Energy World unveils a new section that asks leading players in the industry to give their verdict on a key issue of the moment. This time we ask: Given the outcomes at Copenhagen, what are the implications for the global renewables industry in the year ahead?
Today
In the world of photovoltaics, inverters are the gateway through which the energy of the sun is delivered into a usable format. Discrete, unobtrusive and often fairly non-descript boxes, inverters may be low key, but ultimately their efforts are what make a project economically viable.
Yesterday
Some analysts tip 2010 to be a bumper year for renewables investment in the Asia-Pacific region, largely on the back of 2009 government initiatives that are likely to stimulate widespread adoption and investments in R&D and manufacturing capacity. India's ambition to install up to 220 GW of solar photovoltaic and solar thermal capacity by 2022 stands out. Is that ambition credible?

Even as the UK hailed massive plans for expansion of offshore wind that will see capacity boosted by up to 32 GW, the awkward questions began. Will the supply chain be up to the challenge? Will the right turbines be available at the right time? What about the grid?

In the wake of the September 2009 acquisition of ScanWind, GE has confirmed some design details of its forthcoming offshore wind machine, which is set to mark the company's substantive entry into the offshore arena.

Thanks for spotting this error, according to Himin the correct figure is 100 million USD: http://www.himin.com/english/hmnews.asp

In 2008, solar thermal heating and cooling solutions gained favour in more and more countries,’ says European Solar Thermal Industry Federation (ESTIF) president Olivier Drücke. ‘The solar thermal market in the EU and Switzerland grew by over 60% to 3.3 GWth of new capacity, that is 4.76 million m2 of collector area,’ he adds.

Like many of the current crop of ‘cutting edge’ renewable energy technologies, the concept of extracting energy from waves and tides is not a new one. Indeed, it is well over 100 years since the first tidal wheel was built and the 240 MW La Rance tidal barrage project in Brittany, France, has been operating for well over 40 years. What has changed over the intervening years is the level of urgency with which such projects are now being addressed and the technical achievements by some manufacturers which are making tidal and wave energy a reality.

Material of recent biological origin – such as wood which can be either be burnt directly or further processed to provide heat, electricity or fuel – is defined as biomass or biogas in the context of renewable energy systems.

Blessed with one of the longest coastlines of any country in Europe, large tidal ranges and strong winds, it is perhaps obvious that as the home of one of the largest marine energy resources, the United Kingdom should also sport by far the largest concentration of marine power companies in the world.

It is perhaps because of its reputation as a country with a rain-soaked and overcast climate that solar photovoltaic (PV) has so far made only a minor impact on the UK's renewables sector. This is particularly evident when compared with Europe's market leaders Spain and Germany, and new growth in Italy.

Thanks to its long coastline and maritime climate, the UK has the best wind resources in Europe, and some of the best in the world. Reflecting this, over the last few years the country's wind industry has grown rapidly – reaching a capacity of more than 3.5 GW and becoming the global leader in offshore installations.

The term 'biofuels' has generally has come to mean liquid biofuels for use in transport and is applied to a wide range of products. These fuels may be used in internal combustion engines as replacements for petroleum, diesel oil or other additives.

The UK does well in the small wind turbine industry and is host to some genuine world leaders in the field. Indeed, with more than 15 manufacturers based in the UK alone, a wide variety of designs are available and some 10,000 micro and small wind turbines have been installed in the country since 2005.

The use of tracking technology allowing solar modules to follow the course of the sun (and so optimize the incident angle of sunlight on their surface) can increase electricity production by around a third, and some claim by as much as 40% in some regions, compared with modules at a fixed angle.

The extraordinary development of the photovoltaic market over recent years has emphasized the need for a sustainable method for disposal of PV modules once they reach the end of their life. Recognizing this, the industry has been busy developing strategies and techniques that make the most of the valuable materials contained in their products and simultaneously improve their positive environmental impact.

No typo, 40 is indeed more than 35, but 40 as a proportion of 230 is considerably less that 35 as a proportion of 180. In the first scenario offshore wind accounts for close to 20% of the total, in the later figures this falls to nearer 17%.

It is not a gas appliance and the heat is not transferred. Good Energy assess an individual's solar thermal installation and calculate an expected average annual output. The company then pays the householder a fee for each kWh produced from the system, depending on regular meter readings etc. To qualify for the scheme, owners must sign up for a dual fuel gas and electricity supply contract from Good Energy. The gas supplied, which is used in a conventional boiler for space and water heating, is to some extent offset by the solar thermal installation. A premium on the gas price covers the cost of the reward scheme.

PS. Good Energy currently pay 4.5p/kWh or about US cent 6.75
