"It’s déjà vu all over again," said Yogi Berra. The Hall of Fame catcher could easily have been predicting the coming resurgence of natural gas – fired generation. Yes, a few more coal plants will be completed this year, but don’t expect any new plant announcements. A couple of nuclear plants may actually break ground, but don’t hold your breath. Many more wind turbines will dot the landscape as renewable portfolio standards dictate resource planning, but their peak generation contribution will be small. The dash for gas in the U.S. has begun, again.

As the economy begins to grow again, the banking industry continues to stabilize, and lawmakers work on finalizing climate change legislation, the decisions made in 2010 will lay the foundation for the power industry for decades to come.

China’s largest solar panel maker, Suntech Power, in mid-November announced plans to open a photovoltaic (PV) manufacturing facility in Phoenix, Ariz., in the third quarter of 2010. Roger Efrid, Suntech’s managing director, was widely quoted as saying that the company — which holds 12% of U.S. market share and is looking to reach 20% by 2010 — chose to establish a plant nearer to customers. This was smart business, even though panels would be made from solar cells imported from China, because solar panels are heavy, he told The New York Times: "As the price of solar panels has reduced dramatically in the last 12 months, the shipping costs have become a larger and larger portion of the overall cost of getting these projects to market."

Sempra Generation has conjured up a market plan for producing merchant photovoltaic (PV) power that is inspired. Working with First Solar, Sempra has developed a finely tuned and standardized 1-MW PV power block that can be replicated as needed. Sempra built the modular PV plant on land adjacent to an existing gas-fired plant to shorten the development period, piggyback the power directly to the grid, and enable existing staff to manage the combined plants’ operation.

Renewable Generation in North America

For decades, the solar energy industry has struggled to become cost-competitive with other sources of power generation. Recent technology innovations and creative ways of installing solar generation are beginning to enable solar power to increase its share of the electricity market.

Since Robert Stirling invented the Stirling engine in 1816, it has been used in an array of specialized applications. That trend continues today. Its compatibility with clean energy sources is becoming apparent: It is an external combustion engine that can utilize almost any heat source, it encloses a fixed amount of a gaseous working fluid, and it doesn’t require any water — unlike a steam engine.

A solar thermal demonstration power plant in Jülich, Germany, that was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), was formally handed over to its future operator, the Jülich Department of Works this August.

The first aircraft designed to fly day and night propelled solely by solar energy was unveiled at Dübendorf airfield, Switzerland, in late June. The Solar Impulse has the wingspan of a Boeing 747-400 and the weight of an average family car (1,600 kg) (Figure 4). More than 12,000 solar cells mounted onto the wings will […]

Plans to install a series of solar panel farms in the Sahara Desert to power Europe and North Africa are heating up. The idea was discussed in May as part of the newly formed Mediterranean Union, launched at a summit in Paris, and it now has the backing of both UK Prime Minister Gordon Brown and French President Nicolas Sarcozy.
