Tick tock, tick tock… The ticking sound that our friends in Germany might be hearing is the countdown to 2022, the year in which the country has pledged to be completely nuclear free.

Meanwhile, halfway across the globe, Japan is still dealing with the aftermath of the meltdown at its Fukushima Daiichi nuclear power facility. The disaster greatly damaged public confidence in the safety of nuclear power, leading many countries to question their own commitment to nuclear power.

As Germany, Japan, and other countries seek to phase out nuclear power, they need to design strategies for filling the “energy gap” created by nuclear power’s absence. Renewable energy sources provide the clearest, cleanest path for filling this gap, and many different forms of renewables currently exist as viable options.

Germany-based TimberTower develops massive, easily assembled wooden towers that can be used as the base for wind turbines, much the way wood was used as the foundation for windmills for many centuries. More flexible, renewable and easier to manufacture and produce than metal turbines, the wooden towers make sense for a forest-rich region.

Clean technology company SunPods Inc.—headquartered in San Jose, Calif.—designs and manufactures modular solar array units that help make solar power more accessible and affordable. Unlike conventional customized ground-mounted solar arrays that require extensive onsite assembly and construction, SunPods (which stands for “Sun Power on Demand”) are configured and built in a factory before being delivered to virtually any site — a process that reduces installation time by up to 85 percent, allowing sunny regions to readily harvest the solar power available to them.

Tidal power presents another option for renewable energy for countries with available coastline. IT Power—based in Bristol, UK—is developing an innovative tidal energy device that uses oscillating horizontal hydrofoils instead of traditional rotating blades to generate renewable energy. This pioneering approach offers many advantages over existing tidal stream technology by maximizing the area that can be swept—and hence the power captured—in a given depth of water.

Wind, solar, tidal power, and other renewables all have a role to play in helping countries seeking to move away from nuclear achieve their energy goals. How these countries fill “the energy gap” will be a bellwether for others working to diversify their energy mix.

In front of a packed house of dignitaries, delegates and energy industry leaders assembled for the 2012 World Future Energy Summit in Abu Dhabi, United Arab Emirates, Chinese Premier Wen Jiabao and Korean Prime Minister Kim Hwang-sik each independently reaffirmed their country’s commitment to nuclear (more…)

A U.S. government-funded report has concluded that small, modular nuclear reactors may be the best option for continuing to develop the U.S. nuclear power industry in the wake of the disaster at Fukushima, Japan.

The report, prepared by the Energy Policy Institute at the University of Chicago, said that smaller reactors (more…)

The 138 page document has been released by the New Jersey Governor’s Office that is a master plan on energy for the state. This final version is largely the same as the draft document released last summer, save for a few changes. It lays out the direction for how the state will meet its energy demands over the next (more…)

The good news is that on 8 November the International Energy Agency released its 2011 “World Energy Outlook.”

While it will cheer nuclear advocates, overall the report makes for grim reading.

Pulling no punches, the report states at the outset, (more…)

“Nuclear power is safe and nuclear power is clean and nuclear power is renewable.”– President George W. Bush, September 4, 2006[1]

Since the Fukushima Dai-Ichi nuclear disaster, politicians, business executives and investors around the world have cooled on the prospects of (more…)

An attempt to build the first brand-new nuclear power plant in a generation has taken a step forward now that staff at the U.S. Nuclear Regulatory Commission says plans to build new reactors in Georgia meet safety requirements. The federal regulators issued two related safety reports Friday that cleared the (more…)

Germany has been a leading light in sustainability for many years.

More recently, the country once again showed its leadership in the sector by ditching nuclear power and veering towards alternative energy, unmistakably and inexorably. (more…)

South Korea’s presidential office said in a press release that South Korean President Lee Myung-bak during a two-day state visit by Malaysian King Mizan Zainal Abidin discussed enhancing cooperation between the two countries in nuclear energy and other economic fields. (more…)

Abu Dhabi is commissioning a new set of nuclear plants for the first time in 2018, that will generate 25% of its power. I find this a bit hard to understand, since it’s happening just as countries like Germany and Italy are decommissioning their nuclear power. Also, Abu (more…)
