You might never guess that Jimmy Carter was the first U.S. president to actively support renewable energy by putting solar panels on the roof of the White House. Today the U.S. gets only 6% of its power from renewables. Elsewhere in the world, it’s an entirely different story.
Take Germany, for instance, which in 2000 was already at 6%. That year, it passed the Renewable Energy Act and embarked on its Energiewende (energy movement). At the end of 2012 it generated more than 25% of its energy from renewables—solar, wind, and biomass. It has also succeeded in passing all its benchmarks on the drive to boost that total to 80% by 2050. It’s doing so well, in fact, that it’s upped its 2020 benchmark from 30% to 35% and intends to shut down all nuclear power generation by 2022—a decision made in the wake of the Fukushima nuclear disaster in Japan.
Germany has pursued solar with a zeal found in few other locales, boasing a third of the installed solar capacity in the world.
Utility companies are not the drivers of renewables in Germany. Individuals are, owning 65% of the country’s renewable energy capacity. Utilities, on the other hand, account for only 6.5% of the renewables sector, continuing to focus on fossil fuels.
But renewable energy subsidies are on the chopping block as German officials seek to limit rising energy bills—which help pay for those subsidies—and that looks likely to limit the rate of growth. In addition, a slower economy has already taken a toll on energy consumption.
That reduction in demand has in a way made renewables in Germany victims of their own success. A recent Fitch Ratings report said as much: “Fundamental changes are taking place in German power generation stemming from the implementation of the government’s new energy policy, the Energiewende, utilities’ decisions on capex and asset decommissioning …” However, structural change in the energy market “is also driven by subdued growth in the wider economy and overcapacity that is likely to persist in the coming years on the back of growth in renewables and thermal capacity,” according to the report.
Spain, too, has set a record for energy generation from wind power, according to the blog of the Spanish Wind Energy Association. It now gets about 25% of its energy needs from wind, and from the beginning of November wind was its largest single source of electricity. It also gets about 5% of its electricity from solar.
Here, too, all is not well. The renewables industry exploded in Spain over the past 10 years with the help of the government, which capped power prices and heavily subsidized the sector. Investors from all over the world flocked to take part in its growth, as the favorable environment promised healthy returns.
Years of austerity spurred by the debt crisis are causing the government to rethink its policies—retroactively. In mid-February, the Spanish parliament passed legislation that cut subsidies for renewables; that came on top of a law that taxed power generation but had an outsize impact on renewables. There are, according to Fitch, “at least four negative implications as a consequence of the approval of this royal decree: an uncertain future for renewable projects; legal claims against the government’s decision; a weakening of the investment environment; and increased policy risk.” And Spain is not alone.
“[Southern renewables] are under pressure," writes Federico Gronda, an analyst at Fitch. "Fitch Ratings differentiates between renewable projects in Northern Europe, for which the outlook is stable, and projects in Southern Europe, for which the outlook is negative. Southern European projects are exposed to the risk of the imposition of tax increases and additional operating requirements, as recently observed in Spain and Italy.”
The renewables champion, appropriately enough, is in the north. Iceland gets 100% of its electricity needs from renewables. Geothermal contributes 25%, accounting for some 87% of the country’s needs for heat and hot water, while large hydro takes care of the other 75%. Together, the two sources make up 87% of Iceland’s needs not just for electricity, but also for heat and transportation.
Generation is accomplished in an efficient way, too, with its low and stable electricity cost attracting aluminum smelters, and the ore as well, to its shores—which, in turn, benefits its economy. In fact, President Ólafur Ragnar Grímsson has credited Iceland’s clean energy with helping the country to emerge from its financial meltdown in 2008.
Grimsson pointed out as far back as a 2011 Poptech conference speech that reliable sources of renewable energy offer protection against spikes in the cost of fossil fuel. Not only that, but the country has drawn substantial business investments, not just from the aforementioned aluminum smelters, but also from companies looking for locations to build data centers. And those investments have drawn others, enabling Iceland to recover far more quickly than it might have otherwise.
Consultant McKinsey & Co. has counseled Iceland to take it a step further and export renewable power to Europe as a means to sustain its recovery and build growth. And Iceland is exploring the possibility of doing exactly that; it approached Britain last year about the possibility of an underwater power cable to Scotland that could provide the island nation with as much power as a typical nuclear reactor.
