  • Although Sri Lanka's current carbon footprint is much less compared to other developing countries, the country's existing and planned economic developments have raised the demand for power, resulting an increased GHG (Greenhouse gas) emission. GHG in Sri Lanka is emitted mostly by the burning of fossil fuels for energy generation including transport. However, the most effective way of reducing GHG emissions from the energy sector is to use renewable energy sources. Solar is in the top list of renewable resources that has much potential to use to meet the demand for electricity generation in the country. The purpose of this study is to evaluate the current status of solar power generation and opportunities, barriers for implementing the programs of solar energy in Sri Lanka. Literature reviews mainly used as the primary tool for this study. Sri Lankan government had set the targets for adding 200 MW to the national grid by 2020, and to increase up to 1000 MW by 2025 of solar electricity. To achieve these targets the prevailing barriers have to be considered.

  • The enforcement of the Kyoto Protocol to reduce greenhouse gas is definitely a challenge we cannot avoid. Korea ranks 10th in the world and 1st among OECD countries in terms of the volume of greenhouse gas emission and is expected to join Annex I countries which have to reduce emission after 2012. For the sustainable development, we shouldn't depend upon fossil fuel energy longer. This study will provide preliminary data to developing renewable energy systems for urban generation. There are investigated a recent case study of CONCERTO projects co-funded by the European Commission and analyzed application of renewable energy systems as a urban energy source.

  • As one of renewable energy sources, biomass is playing a major role in reducing the greenhouse gas emission in the UK. The country currently produces about 4.5% (18.1TWh in 2006) of the total electricity generation from renewables, where biomass-based sources accounts for 50% of the amount and the remainder mostly from hydro and windpower. In 2007, the UK government has announced its new energy policy through the Energy White Paper, which includes an ambitious national target of 60% cuts in carbon emission by 2050. Complementary strategic plans in key renewable energy technologies accompanied the Energy White Paper, including biomass strategy, waste strategy and low carbon transportation strategy. This paper summarizes the current status and policy of UK for renewable energy production with focus on the use of biomass and bioenergy.

  • 산업혁명 이후 인류의 화석연료 사용 증가에 따른 이산화탄소($CO_2$) 배출 확대로 온실가스가 지구 온난화의 주된 원인으로 밝혀지면서 선진국을 중심으로 세계 각국들은 온실가스 감축을 위해 경제 개발 도시 환경 정책 등 다양한 분야와 적극적으로 결합하여 신재생 에너지 - 태양광 기술을 이용한 디자인 요구가 급증되고 있다. 따라서 본 연구에서는 이러한 문제를 해결하기 위한 대안의 하나로 태양광 기술을 적용한 공중화장실을 제시하고자 한다.

  • 최근 IMO에서는 온실가스 배출을 규제화 하고자 하는 동향이 있으며 조만간 선박에서 온실가스 배출의 규제가 실현될 것으로 예상된다. 선박에서 배출되는 온실가스는 CO$_2$가 대부분을 차지하고 있으며 세계경제상황에 따른 영향이 고려되지만 지속적으로 증가추세에 있는 CO$_2$를 감소시키기 위한 아국의 대처방안이 필요한 시점이다. 또한 향후 발효될 EEDI를 소개하고 결과적으로 GHG를 저감시키기 위한 방안인 선형개선, 폐열회수시스템, 친환경연료사용기관, SEMP 등에 관한 내용을 다루어 보았다. 이 보고서에서는 GHG를 비롯한 NOx, SOx 및 PM과 같은 유해배출물질을 Top Down방식으로 평가함으로써 선박에서 기인하는 대기오염물질 관련 국내정책 및 해운산업의 장기적인 발전전략에 유용하게 사용될 것으로 기대한다.

  • This paper examines the historical relationship between the Little Ice Age and the Anthropocene, which has not yet been studied. The Little Ice Age is the coldest multi-century period in the Holocene. The reforestation of huge farmlands, abandoned due to pandemics in the Americas, aggravated the cooling weather of the Little Ice Age. It was in the long and severe cold of the Little Ice Age that the transition from renewable energy to non-renewable energy was completed in Britain in the latter part of the eighteenth century, and when the pattern of linear growth in greenhouse gas concentrations was forged in the ecosystems of the Earth. The Little Ice Age forced humans to depend on fossil fuels while the advent of warmer and more stable climate in the Holocene enabled them to start agriculture in an energy revolution 11,000 years ago, thus making the coming of the Anthropocene possible.

  • Methane emission from the enteric fermentation of ruminant livestock is a main source of greenhouse gas (GHG) emission and a major concern for global warming. Methane emission is also associated with dietary energy lose; hence, reduce feed efficiency. Due to the negative environmental impacts, methane mitigation has come forward in last few decades. To date numerous efforts were made in order to reduce methane emission from ruminants. No table mitigation approaches are rumen manipulation, alteration of rumen fermentation, modification of rumen microbial biodiversity by different means and rarely by animal manipulations. However, a comprehensive exploration for a sustainable methane mitigation approach is still lacking. Dietary modification is directly linked to changes in the rumen fermentation pattern and types of end products. Studies showed that changing fermentation pattern is one of the most effective ways of methane abatement. Desirable dietary changes provide two fold benefits i.e. improve production and reduce GHG emissions. Therefore, the aim of this review is to discuss biology of methane emission from ruminants and its mitigation through dietary manipulation.
