A Short Guide To A Secure Future

by Stephen Stretton


Part Two outlines an engineering vision of a Carbon-Free Energy System.

Energy Efficiency or Low Carbon Electricity?

This article provides an economic assessment of two alternative options for preventing ‘dangerous’ climate change in the light of diminishing returns and economies of scale. Energy efficiency is the cheapest way to make carbon savings, but carbon-free electricity provides the backbone of the future energy system and is essential to move to near-zero emissions.

Technology Choice For A New Energy System

In the first part of these notes I consider some desirable aspects of a resilient and low-carbon energy system. I argue that governments should permit and encourage multiple low-carbon energy technologies: including renewable electricity and, under certain conditions, nuclear (fission) power and carbon capture and storage (using fossil fuels and/or biomass as fuels): all the available low-carbon electricity generation options are needed.

UK National Carbon Calculator

How do we reduce emissions by the 80-100% needed to tackle climate change? Using a model of the whole energy system, this spreadsheet shows how it can be done.

Should We Use Nuclear?

One of the most contraversial questions is whether we should use nuclear energy in our bid to tackle climate change. This document argues that we should, under certain conditions.

A Zero Carbon Economy With Nuclear Energy

This article, first published in 2006, sets out a practical plan to decarbonize the UK energy system.

The Cost of Electricity Generation and Related Technologies

A consistent methodology is outlined for calculating the cost of 26 electricity generation technologies globally.
