Future Fuels: What To Expect From Emerging Energy Sources

Last year, renewable energy sources supplied 25% of the world’s power, a 6.3% increase on 2016. A call for evidence from the Department For Business, Energy and Industrial Strategy, published this March, outlines the Government’s …

8 Ways The UK Is Making Strides In Sustainable Energy

Portugal Produced More Renewable Energy Than It Needed Last Month

Last month, Portugal’s renewable energy sources provided more electricity than the country actually needed.

This rather astonishing statistic comes courtesy of Portugal’s national grid (REN) which revealed that in March the country’s wind, solar and hydroelectric plants accounted for 103% of electricity consumption, a figure unmatched in Portugal’s history.

Sadly there were some moments when fossil fuels had to take over to supplement the fact that renewable energy is not a reliably constant source of energy, but overall this compensated for by other periods when renewable energy over-produced.

What’s perhaps most impressive about this news however is that even at its minimum level, renewable energy was covering 86% of national demand and at its maximum it was providing 143% of national demand.

The vast majority of the electricity came from hydroelectric dams and wind which contributed 55% and 42% respectively.

While these months shouldn’t be considered the norm for Portugal just yet, the country’s renewable energy association (APREN) believes that by 2040 renewable energy can safely power the whole of mainland Portugal for the entire year.

Just 10 years after that Portugal has set itself the bold target of becoming completely carbon neutral.

Here in the UK the approach to renewable energy has been enthusiastic but not comprehensive. While Scotland enjoyed some record-breaking months in the last 12-months the country as a whole still suffers from a storage problem.

Because the UK’s weather is so inconsistent there are often times when the production by renewable energy doesn’t meet demand. As such that energy is either wasted or has to be stored.

While Scotland is trialling some experimental large-scale battery solutions, battery storage is still a costly business and to have even a hope of storing enough electricity for the UK we’re probably going to have to wait for more innovation.

The UK Experienced Its ‘Greenest Year For Electricity Ever’ In 2017

The UK enjoyed its greenest year ever in 2017 in terms of how it produced its electricity, the National Grid has revealed.

Proving that renewable and clean energy has been enjoying stratospheric growth, the country managed to break an impressive 13 records around renewable energy.

These included the first day since the industrial revolution where the UK was able to generate electricity without any coal power.

Other records include the first time where over half of the UK’s electricity needs were met by renewable energy.

“It’s been an exciting year managing the many ‘network firsts’“said Duncan Burt, Director of the System Operator at National Grid.

List Of Broken Records In 2017:

  • First 24 hour period without coal generation since the Industrial Revolution – 21 April
  • Longest period without coal generation (40 hours 35 minutes) – 28-29 October
  • Greenest summer ever, with almost 52% of our electricity generation from low carbon sources – 21 June to 22 September
  • The lowest amount of carbon produced by electricity production at any one moment (73 gCO2/kWh) – 2 October 
  • The largest amount of  electricity produced from renewable sources at any one moment (19.2 GW) –21 March
  • Most electricity production from solar power at any one moment (8.9 GW), a quarter of Britain’s electricity supply – 26 May
  • Highest percentage of solar produced relative to national demand (26.8%) – 2 July
  • Most wind power produced in a day (285GWh)– 7 December
  • Most offshore wind generation at any one moment (4.3 GW) – 1 October
  • Most electricity production from all wind generation at any one moment (12.4 GW) – 6 December
  • Most electricity production from hydropower at any one moment (4 GW) – 27 February
  • Record low strike price at the second Contracts for Difference subsidy auction of £57.50/MWh, well below Government guarantee for Hinkley C – 11 September

Figures from MyGridGB reveal the true extent of how renewable and low-carbon energy have transformed the UK’s power grid.

British wind farms generated more electricity than coal plants on more than 75% of days this year, figures show.

The continuing rise of renewables and the decline of the most polluting fossil fuel also saw solar outperform coal more than half the time.

Overall, renewables provided more power than coal plants on 315 days in 2017, or more than 90% of the year, figures up to December 12 show, while coal was beaten by wind on 263 days and by solar on 180 days.

Coal generation only exceeded solar on 10 days from the beginning of April to the end of August.

In total, renewables generated more than three times the amount of electricity as coal over the year to December 12.

The figures reflect a year in which a number of “green” records have been set for the power sector, including the first full day without any coal power on the system, new high levels of solar generation and tumbling prices for new offshore wind farms.

While the UK as a whole has benefitted from this growth in green energy, it is Scotland in particular that has achieved some of the most impressive results.

In October, Scottish wind power created double the amount of electricity needed to power every home in Scotland.

Strong winds and the remnants of Hurricane Ophelia helped send a staggering 1.7 million megawatt hours (MWh) of electricity to the National Grid.

WWF Scotland’s Director Sam Gardner said: “We’re blown away by these figures but they are part of a pattern of increasingly green power production made possible thanks to many years of political support in Scotland. Across the year, renewables now contribute over half of our electricity needs.”

But with daily output from wind only outstripping gas on two days of the year, and renewables overall – including wind, solar, biomass and hydropower – beating the fossil fuel on just 23 days, there were calls for more support for low-carbon power.

Dr Andrew Crossland from MyGridGB and the Durham Energy Institute said: “The Government has focused on reducing coal use which now supplies less than 7% of our electricity.

“However, if we continue to use gas at the rate that we do, then Britain will miss carbon targets and be dangerously exposed to supply and price risks in the international gas markets.

“Clearly, refreshed government support for low carbon alternatives is now needed to avoid price and supply shocks for our heat and electricity supplies.”
