Tokelau – the world’s first solar power sufficient nation

Tokelau, an island nation in the South Pacific, is now completely able to support itself with solar energy. Elly Earls met Joseph Mayhew of the New Zealand Aid Programme to find out how this tiny collection of atolls has become almost 100% self-sufficient in less than 12 months.

Constructing the UK’s tidal network

In November 2012, the UK’s Crown Estate confirmed that three organisations have secured rights to progress with the development of tidal energy projects at eight sites around the UK. Dr Nicola Davies examines the UK’s tidal potential and looks ahead to a surge of new projects and technologies likely to make waves in 2013.

Solar CPV records broken – but can innovation trump mass manufacture?

Records are being broken almost monthly in the concentrated photovoltaic (CPV) solar power market, but at the same time manufacturing plants are being shut down and big players are struggling to compete with their cheaper Chinese counterparts. Elly Earls met CPV analysts Sam Wilkinson and Ed Cahill to find out why driving down costs through incremental innovation could be the only way forward for this struggling sector.

Waste to energy in the UK – Tilbury’s milestone

Green energy proponents in the UK recently celebrated the milestone of achieving a one million ton food waste milestone, with more than one million tons of organic waste being processed into energy annually. Dr Nicola Davies caught up with a recent push to integrate waste to energy projects into the UK’s future energy mix.

Waste-to-energy plants – how they work

Landfill gas-to-energy (LGE or LFGTE) projects enable landfill operators to remove waste gases cleanly and safely, and reduce odours and smog. By generating additional revenue streams from both heat and electricity, gas recovery can also make economic sense. Mitch Beedie reports.

CCS: carbon emission saviour or dangerous earth shaker?

Carbon capture and storage is currently touted as a viable strategy for reducing the environmental impact of CO2 emissions, but recent research suggests there could be more problems than previously realised. Elly Earls met David K. Dillon PE’s David Dillon and Stanford University’s Mark Zoback to find out more.

Smart grid adoption in the Middle East – an oasis of opportunity

The Middle East is in the early stages of smart grid development but accelerated growth, fuelled by large domestic demand, means the door of opportunity for investors and technology manufacturers is open. Ozge Ibrahim reports.

Smart grid solutions to Latin America’s power theft crises

Power theft is a major issue in Latin America where illegal hook ups and black market siphoning costs economies billions each year. Brazil, however, may have found the answer through the establishment of a smart grid system based on meticulous metering. Dr Gareth Evans reports on the advantages of smart metering within Latin America’s emerging economies.

Breed and burn reactors – could recycling waste redeem nuclear power?

Storing nuclear waste is a major challenge but could a new breed of reactor solve this? Mitch Beedie profiles TerraPower’s Traveling Wave reactor to find out whether the next generation of nuclear reactors could run by extracting the energy left over in the spoils of the present nuclear generation.

The race is on – five countries making the most of their marine power potential

Hydro and marine power energy is making a splash worldwide – but which country has the most potential to capitalise? Heidi Vella looks at the top five nations which have the chance to rein supreme in the development of the marine and hydro power industries.
