Pragmatic solar

It is almost certainly the case that humanity has entered a third, historic energy transition. The first two, from wood to coal in the 18th century and then coal to oil in the 20th century, in retrospect seem obvious in their outcomes.

Kinetics and boutique luxury energy

Powering devices by energy derived from movement is increasingly common. For years kinetic energy has powered wristwatch mechanisms.

Why Europe needs an energy roadmap to 2050

Energy systems are like trees. You don't notice the changes from day to day, but over ten or twenty years, the changes can be amazing.

Investment climate for low carbon technologies needs to improve

Further urgent action by government and business is needed to make low carbon energy a reality. The legally binding “fourth carbon budget” requires that by 2025 emissions are halved compared to 1990 levels.

Why I'm sceptical about energy efficiency

I've been struck by the amount of emphasis I've heard being placed on energy efficiency over the past year or so.

Managing the risk in renewable energy

In 2010 global investment in new renewable energy projects exceeded investment in new fossil fuelfired plants for the first time, largely driven by a mix of renewable energy incentives and political pressure to invest in less emission-intensive energy production. Yet although investments in renewable energy plants are growing, so are the risks. Political/regulatory risk and financial risk are on the rise against a backdrop of macro-economic uncertainty, while weather-related volume risk is rising up the agenda as investments in offshore wind farms accelerate.

The European Green City Index

Why cities matter: More than one-half of the world’s population now lives in urban areas, but they are blamed for producing as much as 80% of humanity’s greenhouse gas emissions. Furthermore,increasing urbanisation can negatively impact everything from the availability ofarable land and vital green spaces to potablewater and sanitary waste disposal facilities. Living in such close proximity tends to intensify the demands that urban settlements impose on their surrounding environments.
