Wind energy is often criticised by competing forms of energy generation for some of its perceived aspects. It is said to cause dispatching problems, to be more expensive than fossil fuel, to have a limited global potential, and to represent a high cost to society. This last critique has now been contradicted by GE Energy Financial Services.Read full article
A new study by Clean Edge concludes that generating 10% of the electricity consumed in the US with solar energy by 2025 is a feasible target. The Utility Solar Assessment (USA) Study has presented utilities, solar companies, and regulators a roadmap of how to reach this target.Read full article
The wind sector has been growing spectacularly over the past decade. However, to sustain these impressive growth figures over the next twenty years in Europe and North America, business-as-usual will not be enough. In several European countries, the number of remaining onshore sites for building new wind farms is already declining (see interview with François and Benoît Henriet, 'Barriers for wind projects', on this blog).Read full article
Improving energy efficiency has been a constant concern ever since the oil crisis of the seventies. Today, it is seen as one of the solutions for mitigating climate change and improving energy security. Many numbers for energy saving potentials circulate, but how realistic are these? Despite the current high oil price, energy efficiency improvements these days are not as big as they were during the first oil crisis. Why is energy efficiency so hard to pursue? Have we really exhausted the energy savings potential?Read full article
Power supply systems and power industry in contemporary world are significant, if not the most important, sectors of any company, each country and the entire world economy.Read full article
Experts seem to agree on the fact that the current U.S. electric grid has room for improvement. The rise in the number of blackouts in the US over the last twelve years clearly demonstrates this fact (see my post of 2 June.) However, opinions differ on how dramatic the situation really is.Read full article

February 11, 2016: update of the SCC calculation tool
Availability - the proportion of time for which systems are available to do real work - is becoming increasingly important. It is now the case that most industrial and commercial consumers operate many loads that require higher power availability than that which can be obtained directly from the supply network. Improving the performance of the network is both difficult and expensive, so it is usually left to the consumer to take action to mitigate the effects of poor power quality and availability.Read full article
