This new publication looks at how renewable energy can bring the greatest benefits to host regions.

To benefit fully from cross-border trade in electricity, interconnected countries need to establish a non-discriminatory trading regime based on co-operation and co-ordination, says this study of trade in renewables-based electric power in Europe.

Despite a challenging global environment, the growth prospects of Emerging Asia (Southeast Asia, China and India) remain robust over the medium term, according to the latest edition of the OECD Development Centre’s Economic Outlook for Southeast Asia, China and India.

This new publication looks at how renewable energy can bring the greatest benefits to host regions.

There are no technical or economic barriers to providing all of the world’s energy from renewable sources, according to a recent study. With a concerted effort, including reduced demand and international cooperation, the researchers suggest that the world could be entirely reliant on renewable energy for electric power, transportation and heating/cooling by 2050.

Renewable technologies could supply 77 per cent of the world demand for energy by 2050, according to a report recently published by the IPCC. However, strong and flexible national and international policies are needed to stimulate investment and encourage accelerated use of renewable energy. The most pessimistic scenarios see the renewables share remaining almost static until mid-century.

Connecting Europe and North Africa with a single, long-distance electricity ‘supergrid’ is technically possible and the cheapest option available to meet Europe’s renewable energy targets, according to new research. However, significant political challenges, such as minimising the perception of risk and attracting sufficient investment, need to be overcome.

A new survey from 2010 reveals that upfront costs of up to €14,000 and lengthy payback times can discourage even the most environmentally conscious citizens from installing domestic renewable technology, such as solar panels and wind generators. However, people signing up to a ‘climate pledging’ scheme were still at least 11 times more likely to install these technologies than the average person in the UK.

The available and emerging renewable technologies suitable for urban environments have been assessed in a recent study. Wind and solar technology can now be integrated into building design, and smart grids and metering can more efficiently manage energy production and demand at a local level. Investing in community-level renewable-energy projects can, therefore, help meet the future energy needs of towns and cities.

Establishment of cooperative biogas projects is aided by strong community spirit, regional traditions and farmers' sense of responsibility for their local area, finds a new Italian study. The findings suggest that renewable energy policy could benefit from taking account of community aspects at the local and regional levels.

Some agricultural activities, such as irrigation, could be powered by renewable sources, a new study indicates. Farm machinery could also be renewably-powered, but the machinery would need to be adapted to use renewable electricity, instead of liquid fuel.

Wind and solar energy are effectively limitless resources, but construction of renewable power must compete for a finite amount of land. This study uses a constrained assessment of available land to see whether global energy demand could be fully met by renewable sources. The analysis predicts that by 2070, the world could produce between 730 and 3700 exajoules of electricity per year (EJ/a1) from renewable power, which, even at lowest available land estimates, could meet 2070 electricity needs in most countries.

A 50% renewable-energy supply, which is both profitable and secure, is possible for the UK’s electricity grid by just 2030 according to a new study. The researchers developed a plan for adapting and operating the UK’s electricity grid, designed to be flexibly controlled through smart-grid technology and to overcome uncertainties in renewable-energy supply and demand.

A new study lists 10 factors to help create a closed-loop supply chain for critical materials. However, interviews with key actors in supply chains for photovoltaic (PV) panels and wind turbines suggest that manufacturers and recyclers hold different perspectives on these factors. The research highlights the importance of cooperation between supply-chain actors, as well as investment in technologies and infrastructure for closed-loop supply chains.

A recent study has explored the role that renewable energy schemes can play in promoting sustainable development at the local level. It suggests that more must be done to encourage local investment and involvement in renewable energy projects if global sustainability objectives are to be met.

The effects of market regulation and environmental policy on eight types of renewable energy in the EU are identified in a study which examines nearly three decades’ worth of data. The researchers found that reducing entry barriers is a major driver of renewable energy innovation and that the ability of environmental policy to promote renewable energy innovation depends on the technology; for example, quota systems appear to work better with older technologies.

Researchers have developed a new indicator for policymakers, which shows the strength of renewable-energy technologies for electricity production in a country’s energy security. They compare their Renewable Energy Security Index (RESI) to the carbon footprint, in that it is easy to report and practical to use in energy policy.

Offshore renewable energy sites may provide new 'stepping stone' habitats for marine species, a recent study suggests. They could allow some species to spread beyond their present range and help vulnerable creatures survive in the face of climate change. However, they may also allow harmful invasive species to spread, the researchers warn, and the effects of such projects must be assessed by examining their impacts on the ecosystem as a whole.

Nitrous oxide (N₂O) is a potent greenhouse gas and atmospheric pollutant. A new study proposes tackling both problems by removing N₂O from the atmosphere using a combination of two innovative technologies — photocatalytic breakdown of the N₂O to nitrogen and oxygen, and this within a solar chimney power plant that generates renewable electricity. Although some way off from commercial development, the researchers say this approach is feasible, and they outline how these two technologies can be integrated to reduce the climate impact and polluting effects of N₂O emissions.

Growing demand for biorenewable chemicals could lead to conflicts with food production and unwanted environmental impacts. Against this context, this study investigated different types of feedstock and conversion technologies. The authors recommend use of only non-edible feedstock alongside green and carbon neutral conversion technologies, such as algal fermentation.
