A significant proportion of Eastern Africa is a relatively poor with a predominately rural population and lack access to modern energy services. Reliance on traditional biomass has created severe problems for both the environment and the health of the population: improved access to cleaner fuels would solve this and achieve multiple policy goals. The Global Change Assessment Model (GCAM) is utilised to simulate future scenarios. The study suggests the optimal subsidy policy implementation and recommendations.

Achieving a decarbonised electricity sector is difficult, the main problem lies in integrating new energy sources e.g. Renewable Energy Sources (RES) into existing energy systems. This research is focused on achieving a decarbonised electricity sector in Greece and include both generating and storing clean energy at the local level. The DREEM model was calibrated for the case of Greece and simulated for 3 scenarios. Resulting with 2 policy scenarios.
CO2 emissions from non-electricity energy uses, e.g., industry, transport, and heating, are the greatest impediment to meeting Paris Agreement ambitions. For 1.5°C temperature increase limit; negative emissions technologies will become a necessity and implies a remaining carbon budget of just 200 billion tons of CO2 until 2100. Compared to the 4,000 billion tons of CO2 that would be emitted until 2100 if current trends continue. Future CO2 emissions must be kept within a finite budget.
In 2008, the Climate Change Act was established in the UK, committing to achieve 80% GHG emission reduction by 2050 compared to 1990. The UK electricity supply will need to be largely decarbonised by around 2030. The UK Government has supported both the development of renewable energy and nuclear power, but more the focus on the latter. There has been wide-ranging interest in the possibility of Small Modular Reactors (SMRs), but also risk and uncertainties.
Many European countries has committed to reducing greenhouse gas emissions by 80-95% in 2050, relative to 1990 emission levels as part of the Paris Agreement which set an international ambition to combat climate change. Agriculture contributed 13% of the Netherlands’ total greenhouse gas emissions in 2016 from various soruces. Within the livestock sector, GHG emission reductions will need to be viable from an economic perspective but also meet social and environmental standards.
Part of the transformation to meet climate change mitigation goals will be a reduction in GHG emissions from the energy sector in the EU and Member States. This may involve large economic costs, particularly for investments. The ‘carbon bubble’ is a major financial concern, which may arise through the transition into a low carbon economy. Analysis suggests that investors’ risk perceptions of renewables have more of an impact than the perceived risk of fossil fuels.
Low carbon investments need to increase if the world is to achieve the Paris Agreement aim of keeping global warming below 2°C. A fundamental transformation of the global energy system can be achieved with a comparatively modest increase in overall investments. Shift of investments away from fossil fuels and toward renewables/energy efficiency is needed. Current incentives like the NDCs will not provide sufficient impetus for the “pronounced change” that are needed for the energy system.
The transport sector accounts for almost 1/4 of the EU’s total GHG emissions, and decarbonisation of the sector is therefore crucial. The use of electric powered transport is emerging as the most viable near-term solution to reduce CO2 emissions road transport. The falling costs of batteries means that Battery Electric Vehicles (BEVs) for personal use are becoming more cost competitive, so large potential for Electric Road Systems (ERS) but with substantial uncertainties in costs.
Report from the bioenergy workshop series in Bali with in total 62 participants who attended the event. Among them, 18 were students, 15 were local and national representatives of the government, 14 were researchers, 10 were from private sectors, and 5 were farmers.
Kenya has committed to reduce domestic GHG emissions by 30% by 2030 but also is attempting to grow its economy against a backdrop of international agreements to reduce greenhouse gas emissions. This will mean harnessing the country’s significant renewable energy potential. The study covered three technologies: wind, solar, and the third, geothermal, is more specific to Kenya due to the Great Rift Valley. Overarching areas of interest and policy recommendations are given.
