The Concept and Status of Sustainable Energy

The attention to the importance of sustainable energy has been increasing because of environmental problems and social conflicts associated with energy use. In particular, climate change, mainly triggered by fossil fuel combustion, is one of the crucial backgrounds of the current situation. Energy is connected with economy, environment and social equity, three pillars of sustainable development. Sustainable energy means economically affordable, environmentally sound, and social equitable energy, while contributing to energy security. This is the concept of sustainable energy. In 2013, the UN initiated “Sustainable Energy for All” program, which emphasized energy efficiency, universal access to energy services and renewable energy. In addition, the UN announced Sustainable Development Goals (SDGs) in 2015 which includes “sustainable and clean energy” as the 7th goal among 17 goals. Without establishing sustainable energy system, we cannot realize a sustainable future. Currently, fossil fuel accounts for more than 80% of primary energy supply for all human beings on this planet and nuclear power, another source of risk because of radioactive materials, account for 5 % of primary energy supply. The Paris Agreement adopted at the COP-21 last December announced

the end of the fossil fuel era, while requiring reduction of energy consumption and expansion of renewable energy use. Reduction of energy consumption can be achieved through energy conservation and efficiency improvement. Energy conservation means energy saving with acceptance of lower energy services slightly sacrificing convenience. Energy efficiency improvement means maintaining the same level of energy services with less energy input. The use of renewable energy has been expanded with technology development, citizens’ improved awareness and institutional support. However, lots of barriers lie ahead. Political will and citizens’ involvement for renewable expansion are required.

“How to live sustainably” - Climate change part of our everyday life

Usually we are afraid about climate change and that fear makes us not do anything because we believe we as human cannot do things to help. However, our everyday choice and actions can and actually have a huge impact. [Use spaghetti instead of straw for coffee since the straw is just use 1 time to stir and trashed, Use LED bulbs, Print both sides, Use rechargeable battery, Use tumbler, Unplug chargers, Use less water, Turn multi tabs, Turn boiler temperature lower.] All of these are small actions you can do in your everyday life and that actually matters. Stop eating meat is also something that could help. I know many people wouldn’t like this! But this has a problem. STOP EATING MEAT itself seems too hard, so I propose to do first a day of the week without meat! Most people don't know, but the main problem for our water is meat. Skip meat and cheese one day a week with your family. It would be the equivalent of taking your car off the road for five weeks – or reducing everyone’s daily showers by 3 minutes. Skip steak once a week with your family. It would be the equivalent of taking your car off the road for nearly three months. And if the entire U.S. did not eat meat or cheese for just one day a week, it would be the equivalent of not driving 91 billion miles – or taking 7.6 million cars off the road. I think the most important thing is that first step. If we see change our habit as a wall to climb, we will never cross it, so we should rather define it as a stair with small steps. Everyday let’s go one step, and in no time, you will be on the other side.

The first Zero Energy Housing Complex in Korea

Architectures represent the philosophies, economics, societies and technologies of individual eras and are their products and have been positioned as relics in history. However, to our regret, the architectures, cities and houses where we live daily in the 21st century are still evaluated in the 100-year old ideology of modernism of the 20th century. The Government of Korea is planning to construct the world’s first fossil-fuel zero housing complex in the district where the most low income population in Seoul, South Korea resides. The project is invested mutually by MOLIT, City of Seoul and Nowon-gu District Office to realize energy welfare and welfare for the less fortunate. A house designed and built in such manner will reduce building energy demand for five major energy usage in a house: heating, cooling, DHW, ventilation, and lighting can be reduced by 50%. The rest of 50% is then supplied with electricity through solar PV and heating energy through either geothermal heat pump. In addition, information technology and HEMs is applied for energy maintenance and spatial quality control. Involvement of information technology for energy, comfort, welfare is the vision of future housing and the realization of this process has taken place in Seoul, South Korea and will be completed in 2017. It is hoped that the Korea’s first zero source energy housing validation complex would be a precedent for suggesting a prototype of a zero energy national rental house where people live actually, suggesting a new value of the existence of architectures and housing complexes and showing the global status of Korea in the world and establishing a strategy for responding to global warming.

Climate Change and Energy – The response of the European Union

In December 2015, a historic agreement on climate change was reached in Paris, adopted by 195 countries. This first-ever universal, legally binding global climate deal, the Paris agreement, is a new beginning for international climate action, which requires vigilant follow-up. The EU has played a key role in brokering the agreement in Paris as the fight against climate change is a top policy priority for the EU. It has long shown leadership on climate change internationally, and its domestic action is no different. The EU is committed to becoming a highly energy-efficient, low carbon economy, and has strong track record of domestic action. It has set itself some of the world's most ambitious climate and energy targets for 2030. The EU will reduce its greenhouse gas emissions by at least 40% by 2030 compared to 1990 levels. The EU has an ambitious policy framework in place to ensure that all member states deliver against the strong commitments. Alongside the ambitious emissions reduction target are an EU-wide binding target for renewable energy of at least 27% and an indicative energy efficiency target of at least 27%. Moreover, the EU is on track to meet or even exceed its 2020 target of a 20% reduction in emissions. Between 1990 and 2013, EU's emissions fell by 19% while its GDP increased by 45% over the same period. However, climate change cannot be resolved by one single actor. To that end, the EU is supporting other countries around the word to do the same.

The Danish Transformation Into A Green & Sustainable Nation

When Denmark started its pioneering green transition in 1970s, it started with setting firm policies and ambitious goals. Since then, Denmark has been continuously pursuing its goals and is constantly setting new goals for the future to ensure the sustainable improvement of the Danish climate, energy and environment. Thus, the lecture will be about the Danish experience in transforming Denmark into a sustainable nation with a focus on sustainable green growth. During the lecture, Denmark’s climate and energy policies will be introduced, and Denmark’s success in changing the nation into a low carbon and green society will be included as well. Furthermore, the lecture will include some concrete examples of how Denmark has ensured such a green transformation based on cases from energy and environmental sectors, and specific examples of Danes’ familiarity with green society. Such familiarity spurs from deeply rooted culture of extensive recycling, from clean drinking water from the tap, and from the fact that the Danes can swim freely in the clean Copenhagen Harbor. The lecture will end with the aim of the Danish model, which is to achieve a green and sustainable nation for the Danish population and its future generations.
