Assessing the effectiveness of renewable-specific policies on global renewable capacities
… production of electricity capacity from renewables within their borders. While early policy adopters were mostly developed countries, the number of developing countries adopting renewable-specific policies has expanded dramatically in the past decade. Given that the increase in future …

Alternative and Renewable Energy
… only half that long. A system of alternative and renewable fuels is our only solution to this problem. With proper action and development, a worldwide energy crisis will be avoided. </p><p>We have an abundance of renewable and alternative energy sources that are not currently being used, enough to …

Renewable Electricity Support Policy
Renewable electricity (RES-E) is likely to play a major part in the reduction of Australia’s greenhouse gas (GHG) emissions. Because it is currently dearer than fossil-fuel-generated electricity, support mechanisms are needed to allow it to compete with fossil-fuel electricity. In the thesis I …

Alternatives to the economic rationalisation of renewable energy transitions: the Tsitsikamma community renewable wind farm story
Within the climate mitigation discourse, renewable energy technology is understood as vital to reduce coal energy reliance. This discourse which is deeply anthropocentric in its approach understands 'green' energy transitions largely as reliant on reductionist techno-scientific 'solutions' and …

Fully-renewable and degradable thermoplastic elastomers.
The most common polymers derived from renewable feedstocks, poly(3-hydroxybutyrate), polyglycolide, and polylactide (PLA), have high stiffness and tensile strength, but are inherently brittle, thus limiting the potential for these polymers to replace elastic and ductile polymers derived from fossil …

Multilevel inverters for renewable energy systems
… of reducing these greenhouse gases is to turn to renewable energy sources such as the solar, wind etc instead of coal. Converters play the crucial role of converting the renewable source dc power to ac single phase or multiphase. The advancement in research in renewable energy sources and energy …

Quantifying avoided emissions from renewable generation
Quantifying the reduced emissions due to renewable power integration and providing increasingly accurate emissions analysis has become more important for policy makers in the age of renewable portfolio standards (RPS) and emerging carbon markets. This study focuses on the method of quantifying the …

US Virgin Islands renewable energy future
… DeJongh passed Act 7075, creating an ambitious renewable energy standard. By 2025, the USVI will reduce fossil fuel use by 60 percent. Having committed itself, the USVI must determine how it may meet this goal. In this paper, I analyze the issues and propose specific paths towards the USVI clean …
