This is a guest post by Nick Grealy. Nick Grealy has been the natural gas industry for 24 years and found the first 16 really, really, boring. He sees a role for all energy sources except for coal everywhere. He prefers to produce lower carbon energy, not scenarios and would like to make natural gas […]Read More ..
Sunday 30th April 2017 is seeing record amounts of low carbon generation in Great Britain. At 1030 am, 74% of electricity supplied was from low carbon sources. Renewables (wind, solar and hydro) were providing the bulk of the power. The amount of carbon generated per kWh electricity fell below 125gCO2/kWh Here is some historical perspective for […]Read More ..

- April 12th - Where do British imports come from? (0) (Greenhouse Gas, Imports)In this blog, I assess how we import electricity to Great Britain and evaluate whether this is a low carbon thing to do. I conclude that to reduce carbon emissions from our electricity we should think carefully about where our imports come from and when we do so.

- February 19th - Rising carbon emissions (0) (Coal, Demand, Greenhouse Gas)January 2017 saw a rise in carbon emissions from the same period in 2016. The total amount of carbon rose by 17%. Adjusted for the higher demand in 2017, emissions rose by 8% for every unit of electricity generated. Consistent rises in carbon emissions will represent a Government policy unable to meet the obligations of the Paris climate deal.
- February 11th - The MyGridGB manifesto explained (0) (Coal, Gas, Greenhouse Gas, Wind)The MyGridGB Manifesto proposes one way that Britain can meet its present electricity demands using low carbon electricity. I first proposed it in July 2016 and since then it has been simulated, in real time, on the MyGridGB website. In this blog, we explore the manifesto and how it is structured. After reading it, I invite you to comment and look at ways that the manifesto might be changed in the future.

- January 25th - What can Tidal Power Contribute? (Tidal Power)The UK is committed to carbon reduction in all sectors of the economy be that electricity, heating, transport, agriculture or industry. The £1.3bn, 320MW tidal power station at Swansea Bay could be the next mega-project to help generate sustainable, local energy and assist with climate goals. The question asked is how much it can reduce our carbon emissions per year. I believe that I can answer that using the same tools to run my Manifesto.
- January 21st - Are imports really low-carbon? (Greenhouse Gas, Imports, Interconnectors)Earlier this month, I reported how Britain has recently become a net exporter of electricity to France and has increased imports from Holland. Since writing that post, a more worrying trend has become apparent. Shifting our imports from France to The Netherlands has meant we are importing more carbon intensive electricity than we are generating at home.

- January 15th - Has electricity become the primary consumer of gas? (Gas)My prediction is that in 2016 gas for electricity will have outstripped domestic consumption. That has only happened 4 times in the last 20 years. Britain is evidently getting more addicted to gas.
- January 15th - Peak demand doesn’t cause peak carbon emissions (Energy Storage, Gas, Greenhouse Gas)In this blog, I look how demand fluctuates on a daily and weekly basis and the impact that that has on our carbon emissions. A simple conclusion can be drawn: reducing our electricity demand has a direct impact in reducing carbon emissions.
- January 10th - For 3 months, Britain was a net exporter of electricity to France (Imports, Interconnectors)Britain became a net exporter of electricity to France in the last three months of 2016. Find out more in this blog.
- January 7th - What is replacing coal? (Coal, Wind)Coal generation has dropped from providing 30% of our electricity at the beginning of 2015, to providing less than 7% in the last 6 months of 2016. Furthermore, renewables have overtaken coal in our electricity supply. This may have created headlines, but we need to understand what has replaced our coal power stations.
- January 4th - Returning to work part 1 (Gas, Greenhouse Gas, Wind)Demand falls over Christmas and New Year as many of us are on leave but it quickly returns when we go back to work. In the chart below, I show our electricity use every hour between the beginning of December and 4th January when we return to work.
- December 31st - 2016 in Review (Review)2016 was a momentous year for our electricity supply: the signing and ratification of the Paris climate agreement, the announced closure of all coal power stations by 2025 and of course the launch of this blog. In this piece I pull out what I think are the key messages in GB electricity from 2016.
- December 29th - The carbon value of energy efficiency (Demand, Efficiency)Electricity is changing in the way it is being generated and also in how it is being used. At the end of 2015, I switched my house from incandescent/halogen lightbulbs to LED. In 2016, my family’s electricity consumption dropped by more than a third. But what is the carbon value in reducing our electrical demand?
- December 28th - The return to gas (Uncategorized)Christmas Day 2016 created headlines due to high amounts of low carbon generation and low demand. Since then, the use of fossil fuels increased as Britain returned to work and as wind generation fell.
- December 26th - Where did electricity come from on Christmas Day? (Gas, Greenhouse Gas, Records, Wind)In this blog, I focus on where our electricity came from across the whole of Christmas Day
- December 25th - Cooking turkeys with record amounts of wind (Gas, Records, Wind)On Christmas, the normal rules of providing electricity are a little different. Every day there is a peak demand for electricity which is met by switching on power stations at the right time. In this blog, I broke that our turkey was, in fact, powered by a record percentage of low carbon electricity.
- December 23rd - A new clean energy milestone? (0) (Demand, Greenhouse Gas, Records, Review)It was reported in the Guardian newspaper that the UK hit a "clean energy milestone" after low carbon power "accounted for 50% of electricity generation in the UK in the third quarter". This is based on Government figures here. Is this true for Great Britain? Here are the numbers.
