The concept of beaming power to Earth from orbiting satellites dates back to the 1960s so why is there still an energy crisis? E&T investigates.
Artificial intelligence will soon be helping smart meters run your home, reports E&T.
Water shortages are predicted to be the catalyst for 21st Century conflicts as E&T explains.
The Arctic region has long been viewed as a huge resource for oil and gas but the harsh conditions and tricky economics have made it unappealing, but as E&T reveals that is now changing.
Huge platforms in the Arctic waters off Russia's east coast are defying the elements to produce vast amounts of valuable oil and gas as E&T reports.
Reliable and cost effective storage is key to keeping the lights on in the renewable world, so E&T visited a Cambridge company that thinks they have found a solution.
New information on how biofuels burn is paving the way to greener transport fuels, reports E&T.
As BP works with its partners to contain the oil spill in the Gulf of Mexico following the explosion and sinking of Deepwater Horizon, E&T examines the task at hand and the measures being deployed.
The current focus for the car of the future is plug-in electric vehicles, but there is still a lot of support for hydrogen fuel cells to be part of the solution as E&T reveals.
In the continued drive to combat climate change most of the attention has been on the growth of renewable power, but as E&T discovers the transmission and distribution network is key to reducing greenhouse emissions and without the implementation of a smart grid it will not deliver.
To many opponents of a renewed nuclear future, the lack of a coherent long-term plan to manage waste is the biggest stick to beat the industry with. The announcement late last year that the US had abandoned its plans for a deep geological storage repository at Nevada's Yucca Mountain - a much vaunted solution - has only created an atmosphere of uncertainty.
E&T spoke to Steve Frishman, a geologist at the head of the Agency for Nuclear Projects office at the Office of the Governor of the State of Nevada and a man who has been involved in the Yucca Mountain project since the beginning, about why the nuclear waste repository has failed to meet expectations.
Biofuels are vital in the fight to reduce carbon emissions and combat climate change. But developing a sustainable biofuel has proved challenging, but the latest advances with microbes and algae could provide the answer
What are the secrets of sustainable living? E&T looks at towns and cities from around the world as look at renewable energy, recycling and green living as they try to curb their carbon emissions to combat global warming.
What caused one of the world's largest power blackouts in history? And is it the first of many? E&T investigates.
Reducing the environmental impact of the billion or more phones that are sold each year.
With wind energy moving in to the mainstream, turbine manufacturers are striving to increase productivity and quality while driving down costs. E&T visited several Vestas facilities in Scandinavia to assess their improvement efforts.
As E&T discovers, there has been excellent progress in sustainable buildings, but much more is still required.
In the clamour to cut carbon, are wind farm concerns going unheard? E&T investigates.
Small-scale solar photovoltaic plants are proving to be an efficient way of generating electricity locally. E&T visits a 1MW facility on Spain’s Costa del Sol to look at a facility in action.
There has been much rhetoric about how the world will meet its emissions targets, but the action has not matched the oratory. E&T looks at the UK’s latest initiatives.
Can a new generation of passive sonar systems help man and animal coexist in the oceans? E&T finds out.
Could active sonar systems, trained by humans, help unlock the UK’s tidal energy? E&T finds out.
With the unveiling of the first prototype - the HB-SIA - the Solar Impulse environmentally friendly aeroplane project has entered its final test phase. E&T flew (on a fossil fuel powered plane) to Switzerland to find out more.
The ability of the UK power grid to support the growth of electric cars has been called into question, but as E&T discovers there is more than enough electricity to go around.
PCs could be made more energy efficient with emerging technology, reports E&T.
A race car built with vegetables and powered by cocoa butter may be green, but does it go? E&T investigates.
Old gas-guzzling cars are reaching the end of their tenure and, as E&T explains, financially crippled car makers are in a race to hit upon the sustainable car for the future.
When you picture green cars, the last thing on your mind would be the typical 200mph racing car. But, as E&T discovers, several new racing series are shattering that conception.
...that’s clean energy and not mutated viruses, by the way. E&T reports.
People who shop on the web or work from home could be increasing carbon emissions rather than helping to reduce them, according to a new report from the Institution of Engineering and Technology (IET).
E&T video: monitoring climate change at the Met Office
We speak to David Hein at the Met Office about its mathematical models used for monitoring and predicting climate change.
Energy strategies
Jonathan Smith from Rockwell Automation talks about why you should have an energy strategy for the future in this video.
From Abbey Road to prehistoric zoology, E&T videos span the engineering and technology community.
Sustainability commentary
Copenhagen COP15 - Final day 19 December 2009
Leaders deserted the sinking ship that is the Copenhagen climate talks as fast as they could on Friday evening proclaiming success from what at best is a rag-tag document that may well prove not to be worth the paper it's printed on.
