With an increasing proportion of our electricity coming from intermittent renewable energy sources like wind & solar, new strategies are needed to match electricity supply and demand.
At any moment, the amount of electrical power generated, and consumed need to be in balance - too much or too little, could lead to power-cuts, or wind /solar farms being turned off when they could be delivering power.
Traditionally, supply and demand were matched by ramping fossil fuel and hydro-power up and down, but increasingly as fossil fuels provide a smaller share of electricity, this needs to be supplemented by adjusting demand to match supply, and by storing power for later use.
Examples include running industrial processes at times when there is spare generation available on the grid, letting the grid operator control when out immersion heaters run, and smart electric vehicle charging / vehicle to grid.
Gary's talk will discuss these demand side management, and related smart meter / tariff arrangements and how these interact with the emerging Internet of Things.".
Ed Gemmell, Founder of No Disposable Cup Day, Managing Director of charity Scientists Warning Europe, will be introducing us to ‘No Disposable Cup Day’ and talking about the environmental disaster associated with the UK’s insatiable coffee habit. He will then comment on the takeaway packaging industry, plastic lawns, plastic diets, Tik Tok and what we can do to fight plastic pollution and climate change in our own lives.
Brian will be talking about the ‘End Plastic Soup’ initiative, which was started by the Rotary Clubs of Amsterdam in 2018. A member of Marlow Bridge Rotary Club, Brian is an Ambassador for this initiative. Brian will cover plastic waste and micro-plastics pollution in the River Thames, plus the global problem with plastic waste and its solutions.
Paul Bolton is the President of Marlow Bridge Rotary Club (MBRC). Paul will give a talk on how MBRC supports various community projects both locally and internationally.
The speaker was Lars Boerner, the Managing Director of VerdErg. The company envisions a future where low head hydropower can be as reliable and as cost effective as energy from fossil fuels, but with a considerably lower carbon footprint.
VerdErg technologies could minimise negative impacts to rivers, such as the Thames, while generating clean energy to local households & businesses.
Marlow Energy Group, in association with IDDEA, held a ‘Marlow Solar Streets’ Zoom event promoting installation of solar PV in Marlow.
IDDEA have already installed 700 solar projects in the south and south-west. The highly competitive figure of £4000 for 12 panels (4kWp total) is being offered on the basis that IDDEA can make at least 10 installations in and around Marlow. This has not been a problem in other towns such as Henley, Thame, and St Albans.
The Zoom presentation will describe the financial savings, environmental benefits and how to apply for the initial survey.
This exciting venture is supported by Marlow Town Council’s ‘Sustainable Marlow’ campaign and by many local groups.
