PARIS (Reuters) - Europe could have saved itself $100 billion by installing solar power panels in sunnier countries and wind turbines in windier places, the World Economic Forum’s “Future of Electricity” platform said in a report released on Tuesday.
The report, written with consultancy Bain, added that another $40 billion could have been saved by better cross-border coordination and bigger power cables between countries.
It said that even though Spain gets about 65 percent more solar energy than Germany (1750 kilowatt-hours per square meter/year compared to 1050 kWh/m2 for Germany), Germany has installed about 600 percent more solar photovoltaic capacity (33 gigawatts compared to 5 GW).
But while Spain has less wind than northern European countries, it has still installed 23 GW of wind power capacity.
“Such sub-optimal deployment of resources is estimated to have cost the EU approximately $100 billion more than if each country in the EU had invested in the most efficient capacity given its renewable resources,” the WEF report said.
It also said that overinvestment in renewables has created huge overcapacity in Europe, weighing on utilities’ profits.
Over the past five years 130 GW of renewable generating capacity and 78 GW of conventional capacity have been added to the system in the EU, while only 44 GW of conventional capacity has been retired, the WEF report said.
At the same time, growth in demand for electricity in Europe has flattened to zero percent in 2007-2012, compared with an annual growth rate of 2.7 percent since the 1970s.
As a result, return on invested capital has dropped 4.8 percentage points to around 6 percent. While the United States has seen a similar slackening of demand, retirement of old plants has more closely matched the advent of renewables, and American utilities have preserved their profit margins.
The report supported industry calls for a system that would pay utilities for keeping generating capacity on standby but acknowledged that “a strong consensus has yet to emerge on the optimum mechanisms for ensuring reliability and flexibility”.
Utilities such as Germany’s RWE and E.ON desperately want government help through the creation of a “capacity market” to fund the continued operation of their otherwise unprofitable gas and coal-fired plants, saying such a mechanism would boost security of supply, but German Chancellor Angela Merkel said earlier this month she does not support this idea.
