Filling the GAP

By Dave Elliott

A group of UK notables, including Sir David King, Lord John Browne, Lord Nicholas Stern and Lord Martin Ryle, has launched a proposal for a 10 year Global Apollo Programme of science-led research and development (R&D) to develop clean energy technology fast to combat climate change. One of the other proposers, former Cabinet Secretary Lord O’Donnell, told BBC News: ‘People never believed we could put a man on the Moon – but we did. People don’t believe we can solve climate change – but we have no choice.’ (more…)

Reactions to climate uncertainty

By Dave Elliott

Renewable energy has benefited from concerns about climate change. But in some countries there are doubts about whether climate impacts will be severe and in some there are no significant climate policies. Contrarian views may be in a minority in most places, but much has been made of the apparent slowdown in average global temperature rises in recent years. Indeed some sceptics claim that this refutes all the climate models, with some pointing to a 17-year or more period when the running average did not indicate a rise. So it’s claimed we don’t need to rush ahead with renewables. (more…)

Germany stays on course

 By Dave Elliott

Germany is sticking to its ambitious plan to get at least 80% of its electricity from renewables by 2050. As part of that, it aims to support the construction and operation of 20 offshore wind farms, 7 GW in all, and that plan recently received a boost, with the European Commission agreeing that it did not conflict with EU state aid rules. The 17 wind farms in the North Sea and three in the Baltic will further EU energy and environmental objectives without unduly distorting competition in the Single Market, the EC said.

France – 100% renewable by 2050?

By Dave Elliott

France is heavily reliant on nuclear power, which supplies around 74% of its electricity, although some of that is in fact used to run the nuclear fuel system, including fuel fabrication and reprocessing. It has often been said that it would be impossible to phase out nuclear in France. The Hollande government has promised to cut the proportion back to 50%, and has a quite ambitious programmes for renewable energy (32% of all energy by 2030) and energy saving (a 50% cut in all energy use by 2050). But going further has often seemed a fantasy, not least in terms of cost. However that’s now changed, with a new government  report suggesting that it would be possible to move to 100% renewables.

UK renewables hit 19% – but are hit back

By Dave Elliott

The output from the UK’s 24 GW of renewables was 64.4 TWh in 2014, 19.2% of annual UK electricity supply, overtaking that from the UK’s troubled nuclear fleet, at 63.8 TW in 2014. Wind led, at 31.6 TWh, 9.4% of UK electricity, solar supplied 3.9 TWh (1.2%), hydro 5.9 TWh (1.8%) and bioenergy 22.9 TWh (6.8%). And Scottish renewables supplied the equivalent of 49.6% of Scotland’s electricity use, led by on-shore wind. www.gov.uk/government/uploads/system/uploads/attachment_data/file/416310/PN_March_15.pdf

Green energy in the EU

By Dave Elliott

In January last year the European Commission (EC) suggested that the EU should cut carbon emissions by 40%. Although it’s conditional on other countries setting significant targets, it’s a bold target, leading the way forward. But sadly the EC faltered on setting ambitious specific targets for how to actually do it. It only raised the targeted share of renewables in primary energy to 27% by 2030, up from the existing 20% by 2020 target.

Renewables in the USA

By Dave Elliott

The USA current generates nearly 15% of its electricity from renewables and they are still expanding quite rapidly, with wind at 66 GW and PV soon at 20 GW. This growth has mainly been driven by the simple fact that these options are getting competitive, although, despite continuing political uncertainties and delays, state and federal tax concessions, support schemes and production quotas have obviously also helped.

Green energy in Africa

by Dave Elliott

Africa has amongst the world’s best renewable energy potential globally, given its climate, with solar an obvious choice, hydro already being well established and wind beginning to be taken up. Biomass and, in some areas, geothermal, are also very significant options. However, hydro apart, the continent only just started to exploit these resources. (more…)

Renewables in Russia – not much interest

By Dave Elliott

Russia’s renewable energy potential is vast. A 2003 IEA report said that, overall, renewables with economic potential corresponded to about 30% of the country’s then total primary energy supply, while the technically viable potential was estimated to be more than 5 times greater than its energy needs. Only about 20% of the hydro resource has been tapped so far, and the target for new renewables is very  low. (more…)

Renewable energy in the Middle East…and beyond

By Dave Elliott

Despite the political turmoil, renewable energy projects are proliferating in the Middle East and North Africa (MENA) region, PV solar and Concentrating Solar Power (CSP) especially, as you would expect: this is a sun-drenched part of the world, with a lot of free desert land area. Saudi Arabia is one the leaders, with plans for installing 41 GW of solar (PV and CSP) by 2032, although that target has now been put back to 2040.
