Our ACT Energy & Built Environment group is all about taking meaningful actions to reduce greenhouse gas emissions, doing our bit to tackle climate change.

The working group meets regularly every four weeks (by Zoom or in person).  We have combined these meetings with those of the Transport group. Please contact the group coordinator if you would like to join us.  Everyone is welcome to ask questions, discuss topics, plan or implement the actions needed to achieve our purpose.

We need to cooperate with others, nationally, regionally and locally.  Our focus, however, will be on working locally within Teignbridge.  Not only do we need to learn/share best practice, but we also need to bring our community with us if we are to be successful in delivering a sea-change in attitudes and behaviour.

Energy and Built Environment covers:

  • Housing and buildings
  • New development and existing stock
  • Infrastructure, including all those associated with transport
  • Energy services and utilities, including energy generation

We have developed a number of tools and gathered data to help everyone understand and tackle their Carbon emissions. This starts with us as individuals and extends to households and public/private organisations, or can cover a particular geography/sector within Teignbridge.

There are several activities the working group undertakes, including providing data/analysis and support to anyone that asks. Below are our current areas of focus and links to more information/support.

We use the terms Carbon and Green House Gas (GHG) emissions interchangeably to refer to all gases that contribute to atmospheric warming.  These are usually measured in terms of weight of CO2 equivalent, e.g. kg CO2e or t CO2e.

Energy & Carbon

Nearly 75% of GHG emissions come from burning fossil fuels for energy!

The government’s stated net zero Carbon ambitions and other related policies are of course welcome.  We do not, however, think these are coherent or well thought through at this stage.  In particular, we do not think there is an energy or Carbon strategy to get us to net zero, even by as late as 2050.

A more coherent approach to decarbonising everything would be to follow one of the widely accepted Energy Hierarchies. These hierarchies can differ slightly in their steps, but all start with reducing energy consumption as the most important and effective. Technological solutions on their own, whether in improved efficiencies or more renewables, will neither reduce GHG emissions enough nor can they do it quickly enough.

Nevertheless, we will need the technological solutions to complete the task.  Even if we were to make significant inroads into reducing our energy consumption, it would be impossible to reduce this to zero.  Therefore, we need technological solutions to make sure the remaining energy we require has low enough GHG emission that the natural environment is able to absorb (sequester). 

With current trends, we will have emitted enough GHG within 5 years to exceed the Paris Accord’s limits.  To stay close to the 1.5OC temperature rise limit, we will need to get to net zero GHG emissions by 2030.  See our 2019 report to the council and the latest explanation of what is causing the climate transformation, what it’s consequences are likely to be and what needs to happen to mitigate this.

There are a lot of conflicting reports on the next new technology that will ‘solve the problem’. We do not think there is a ‘silver bullet’. We also think there is much confusion between generating low-Carbon energy and how we use energy in general. For example, both electric vehicles and heat pumps may be sold as ‘green’ or ‘low carbon’, but the energy needed to power them has to come from somewhere.  Some would say, we’ll just have more Renewables.  It’s of course not that simple. There are many big technical/logistical hurdles to overcome.  Simply moving all our current transport and heating energy demand to renewable electricity is impossible for the electricity grid to deliver, certainly in the time available.  See the TECs report on options for Net Zero for Teignbridge.

So why are ACT and many others still working hard if things are difficult or even impossible?  Well, we think there are solutions, but they need everyone to take part and ‘do their bit’.  If you are interested in this and the discussion around the subject of how to decarbonise quickly, effectively and without pain, please join us.  Here are a few links we’ve been working on which you may want to look into and contribute to:

We understand that we are all different with varying levels of knowledge, effort and time. Our circumstance also vary, so actions we take to mitigate climate change will inevitably be personal. This is why we do not prescribe actions, instead we provide approaches and information to help you decide what actions are appropriate to you. We are here to help you answer the questions you ask, such as but not limited to:

Housing

We believe that whole housing retrofit will be a critical area to address.  While there have been several government schemes, including the most recent £5,000-£10,000 green homes grant initiative, the local market and supply chain are not sufficiently developed to deliver quality retrofits.

We have been working with Devon County Council and Community Energy groups to stimulate this market for the benefit Teignbridge residents. Here are some options:

Energy group meeting notes (21.11.24) The next regular meetings will be (no December meeting): Thus. 16.01.25 at 19:30 and every 8 weeksThus. 13.02.25 at 16:30 and every 8 weeks. This will be a face-face, probably in a public place that serves food/drinks (details to follow) Here is what we covered: We had a wide-ranging discussion… Read More...
Energy group meeting notes (24.10.2024) Here is what we covered: We looked at the pros and cons of pico-hydro generation, see picture of the installation. Even with a flow of over 10 L/s it is difficult to extract much power without a significant head. At 3m head, this would theoretically generate ~300 W, but only… Read More...
Energy group meeting notes (26.09.2024) Here is what we covered: ACT and TDC have piloted a new joint initiative to help householders and businesses better understand their use of energy, starting with electricity. Here is a link to this behavioural change session if you’d like to take advantage of this free offer. We fed back… Read More...

As a CIC we stayed clear of any party political discussions, but we did look at some of their policies and actions, specifically in relation to the climate and energy policies. ACT covers two… Read More...
