Meeting Our Energy Needs

Capacity Factors

I was just going to explain briefly about what ‘capacity factor’ was but while I am on the subject I decided to make a couple of other points. What is ‘Capacity Factor’ It is the amount of energy produced by a power plant divided by maximum possible. For example if a plant is theoretically able […]

TASC Leaflet – Meeting Our Energy Needs

This is a copy of the leaflet produced for Together Against Sizewell C (http://www.tasizewellc.org.uk). The leaflet can be downloaded in pdf format from here. Before We Begin Electricity is less than 20% of our energy needs – we use oil for transport, gas for heating etc. So if we had 20% of our electricity produced […]

Using Energy and Thermal Efficiency

This is a follow on from my previous post – Energy and Temperature and looks at how we can extract and use energy from a system and what constraints there are in terms of efficiency. Energy Differences Let us consider two water containers. We have just filled one with water and it connected by a […]

Energy and Temperature

First of all I am going to talk a bit about energy. It is not going to be a scientific analysis but is designed to give you a feel about how energy behaves. We are going to do a Gedankenexperiment (thought experiment). Let us consider a pool table with no pockets. Also the pool table […]

What Do We Use Energy For?

We would like to refer to proper studies on what is our energy use. Unfortunately most of the studies are based on greenhouse gas (GHG) emissions rather than energy. Although the two do not correlate exactly1 in some places we are going to use CO2 emissions as a proxy for energy consumption. This should not […]

Power for the People or Profit for the Few?

The changes to the increasing complicated electricity market and the domination of electricity supply by a few big companies brings into question whether the UKs energy policy is being designed to help those big companies of the consumers and tax payers. Ownership or control of energy supply has always been a major source of power […]
