Smart grids and renewables: the best combination for saving the planet

Renewables can guarantee a secure and reliable electricity supply thanks to smart grids. That is the leading conclusion of a new study by Greenpeace and the European Renewable Energy Council presented this week in Madrid (Spain). The report also highlights the low economic cost of this transformation: less that €5 per annum per household.

The report entitled “Renewables 24/7 – Infrastructure needed to save the climate” shows how the world’s power grids could be transformed to support a power mix comprising 90% renewable energy by 2050. The transformation would be achieved at a modest level of investment, presents a huge market opportunity for ICT companies, and would enable huge cuts in greenhouse gas emissions.

The study explains how mini-grids and smart-grids could be connected intelligently with a super grid to provide reliable around the clock supply without any need for coal fired or nuclear power plants. The study also proposes a specific grid reinforcement and expansion plan for Europe, including a cost analysis.

"With smart grids we basically merge the internet with the electricity grid", says Greenpeace International senior energy expert, Sven Teske. "Building up smart grids is a huge business opportunity, especially for IT companies. In Europe the annual investment needed will be around €5 billion. That would cost a European household less than five Euros a year. To unlock this urgently needed investment in new climate friendly infrastructure, we need energy policies which support the transition towards close to 100% renewables in the power sector," he adds.

The 2008 EU 27 Energy [R]evolution scenario showed how Europe could achieve 90% renewable energy supply by 2050. The new report compared 30 years of weather data with European annual demand curves and concluded that with the existing grid there is only a 0.4 percent – or 12 hours a year – chance that high demand correlates with low solar and wind generation. The proposed grid reinforcement would remove even this small uncertainty and guarantee reliable power.

First step to Euro super grid

This new publication comes on the heels of a political declaration of a 'North Seas Offshore Wind Initiative'. On 7 December 2009, ministers of the North Sea Countries announced that they would develop an offshore grid to enhance the integration of renewable energies such as offshore wind farms. The offshore grid will be one of the first steps toward a European super grid.

"We welcome the EU initiative for a better use of renewable energies which shows we can deliver a smart, super grid and expand renewable energy supplies in parallel", says Christine Lins Director General from EREC.

"The global market for renewable energy could grow at a double digit rates until 2050, and overtake the size of today’s fossil fuel industry. Currently, the renewable energy market is worth €100 (EREC will send data) billion and doubling in size every three years. The global renewable market will go hand in hand with the development of smart grids, when the combined share of wind and solar photovoltaic power exceeds roughly one third of the total power generation," she claims.

Renewables 24/7 is part of Greenpeace’s Energy [R]evolution scenario, a comprehensive vision for a climate friendly global energy supply.
