The contribution of small-scale wind and photovoltaic renewable energy sources to the Scottish energy mix.
Energy needs in the UK are currently met primarily through the use of finite resources, such as oil, coal and gas. The use of these fuels has led to an increase in greenhouse gas emissions. There is a need for a more localised and sustainable energy source to meet the demands of our cities. …

The ecosystem of renewable energy shift and its future dynamics
Substituting non-renewable energy for renewable energy plays an important role for our sustainability, which is the common goal for human beings. However, several strategies by governments and companies exist to make this shift, because the priority of each strategy mainly depends on the relative …

The impact of energy on sustainable economic development in Uganda
Energy is a very important resource for national development. Uganda's energy mix comprises mainly biomass, petroleum products and electricity. Biomass is the main source of energy, contributing 92.3%. Petroleum contributes 6.3% and electricity 1.3% of the total energy consumption. The contribution …

Evaluation of Residential Real Estate Energy-Rating Systems in Germany, and their Applicability to the United States
Energy efficiency has become an increasingly important topic as economies globally race to combat climate change. Real estate is a major driver of global emissions, however also a key potential area for emissions reductions. In Germany, residential real estate has been identified as a major source …

High–fidelity numerical modelling of ocean wave energy converters
The exploitation of ocean wave energy as a renewable energy source is a challenging task. However, once economically viable, wave energy can make a significant contribution to the global renewable energy mix and, thereby, aid the fight against climate change. To support this action, researchers and …

Rural Energy Development: Are Mini-grids the solution to East Africa's Energy Crisis
… Africa continue to grow, the demand for modern energy will correspondingly increase. The current energy policy and limited overall access rate is not prepared for this massive demand increases and presents a major hindrance to country growth potential. This thesis focuses on the countries in …

Computational frameworks to enable accelerated development of defect-tolerant photovoltaic materials
Widespread adoption of carbon-free energy technologies, including and especially photovoltaics (PV), is vital to address the issue of climate change. Absent sweeping policy action, this will only happen if these technologies become the most economically viable energy source. While PV has become …

Impact on heat rate and subsequent emissions due to varying operation of coal fired power plants
Energy mix modellers often use a constant emissions factor model, which more or less implies a constant heat rate, when trying to show the emissions reduction benefits of integrating renewable power generation system on the grid. This approach does not consider the fact that there is a …

Carbon capture and sequestration : an option to buy time?
… options of reducing economic growth, increasing energy efficiency, changing the energy mix and CCS are assessed simultaneously. An important question is whether CCS is a temporary or long-term solution. The results show that in the middle of the 21st century CCS has its peak contribution, which …
