  • Sustainability in bioenergy
    Biomass is a very versatile resource that can be used to produce heat, electricity, transport fuels and a range of chemicals and materials. It is used in all these applications today, and its future demand is estimated to grow substantially.
  • What are the prospects for wind power development through 2012 and beyond?
    Many people interested in renewable energy perceive wind power to be one of the most mature and low cost of the renewable technologies. And with over 200 GW now installed worldwide in nearly 100 countries, it’s not difficult to see why. But the industry has not been without its troubles in recent years. The credit crunch especially provided a difficult landscape for developers to obtain investment in new projects, and important markets such as the U.S. have been on something of a roller coaster over the past few years; the emergence of new reserves of shale gas in the country has compounded problems. And even in China, which has seen a massive surge in development over the past few years, recent months have seen problems with manufacturing overcapacity, with the Government in May halting all new project approvals (though it has recently cleared the way for a further 26 GW of projects, according to RECHARGE magazine). But with all the challenges, the wind industry continues to innovate around areas like aerodynamics, drive train and intelligent operation, as it strives to improve performance and reduce costs further.
  • What are the prospects for competing solar electric technologies?
    The argument about who wins – Solar Photovoltaics (PV), Concentrating Solar Thermal Power (CSP), or Concentrating PV (CPV) – is currently all the rage. But in reality it is too early to identify winners and losers in the overall solar industry. The solar industry, while growing exponentially in recent times, remains in startup phase compared with conventional power, and is now beginning to experience challenges with rapidly decreasing incentives, subpar availability of transmission and distribution, and for PV, almost overnight growth from MW to multi-GW level of demand.
  • Building blocks: how can renewable energy reach its potential?
    Announcing the latest Renewable Energy Focus interactive webinar, in association with the World Future Energy Summit - Abu Dhabi, 2011.

  • Obituary of Hermann Scheer: the passing of a pioneer Obituary of Hermann Scheer: the passing of a pioneer
    This week saw the very sad death of Dr Hermann Scheer, in many ways the father figure of German renewable energy, and a hugely influential figure worldwide. He was a fighter who seemed to relish his battles, and an inspirational, irreplaceable character.
  • Renewable energy in from the cold? Renewable energy in from the cold?
    One of the hot topics for debate at the forthcoming Windpower 08 event in Houston, Texas, will be transmission. Following Texas' lead, four states possessing the wealthiest renewable resources in the Western USA have enacted their own laws to create Renewable Energy Zones, and define the transmission infrastructure that needs to be built to connect those resources to main transmission highways. Lyn Corum reviews the progress made to date in these states.
