Policy sparks interest in alternative fuels
1 August 2006
Fossil-based fuels will remain the primary energy source for power generation and transportation in the foreseeable future. But as the scope and scale of projects aimed at developing alternative fuel sources grow, they will play an increasingly significant role in the US' energy future, writes Anne Feltus
The ethanol boom
1 August 2006
The North American biofuels business is expanding rapidly, although there is still considerable uncertainty over how the industry will take shape. Investors rushed to buy shares in initial public offerings (IPO) held by several ethanol producers in the first half of 2006, but that trend seems to be fading, with reports that as many as 20 IPOs were withdrawn or delayed in late June, WJ Simpson writes.
Let's get together
1 August 2006
The controversial Nam Theun 2 hydropower project shows big-ticket regional energy projects can happen – but not all grand plans will see the light of day, writes Martin Clark
Carbon chaos

BTL the next step on from GTL
1 July 2006
The GTL industry is in its infancy, but is already being thought of as a stepping stone to a much bigger idea – fuels from renewable biomass. Tom Nicholls writes
Wind brakes
1 April 2006
THE ERA of large-scale offshore wind-energy in Europe and the US is approaching fast, but perhaps not quite as fast as some governments – eager to find green alternative power sources – would like, writes Ian Lewis.
No longer treading water
1 March 2006
Tidal power is a relative newcomer to the renewables party, but its predictability – an advantage over competing renewable energy sources – is raising its profile in Europe and Asia, writes Chris Webb
Burying the problem
1 March 2006
The goals of economic growth and reducing greenhouse-gas emissions are mutually exclusive, if growth is dependent on burning of fossil fuels. A switch to nuclear generation is a partial solution, but brings intractable environmental issues. Liz Bossley looks at carbon capture and storage as a possible solution
Weighing up the options
29 November 2005
THE FIRST year of the European Union's (EU) Emissions Trading Scheme (ETS) is drawing to a close. Emissions of greenhouse gases in 2005 are close to being verified and installations affected by the scheme are counting the cost of compliance, writes Liz Bossley.
Biofuels: no magic bullet for EU
29 July 2005
European Union (EU) will be hard pressed to meet its targets for increasing the use of biofuels. The high price of feedstock and the shortage of suitably large areas of land for growing the crops make them a much more marginal commercial proposition than in other markets, such as Brazil, writes Dan Lewis, director of environmental affairs, at the Stockholm Network
Solar power: Shine on
29 July 2005
BP made a profit on its solar business last year and the world solar market is growing by 40% a year. But while momentum behind the business is building, the economics of solar power generation continue to depend on state support, reports James Gavin
Renewables: a growth sector
1 November 2004
Technology: No longer a dirty word
1 October 2004
The importance of coal as a primary energy source is unlikely to diminish in the near future, but some of the environmental stigma attached to it might, as new clean-coal technologies seek to bring emission levels tumbling. Martin Clark reports
Room for improvement
1 September 2004
Few believe that the European Union will meet its 2010 renewable energy targets, but its efforts so far have not been without merit. New policies and technologies should see the use of renewables grow in importance over the next decade, writes Cris Heaton
A breath of fresh air blows east
1 September 2004
The European Commission has admitted that the EU's original member states will miss 2010 targets for power produced from renewable sources. And unless accession countries step up their efforts significantly, experts say the expanded EU is unlikely to meet proposed new targets for 2020. NJ Watson reports
Energy policy: there’s no pleasing some people
1 July 2004
While the federal government's White Paper on energy policy—Securing Australia's Energy Future—did not contain any major shifts in policy, and introduced several new initiatives, it has caused controversy because of its omissions. Derek Bamber reports
