High Quality Content by WIKIPEDIA articles! A zero-carbon city is a settlement powered exclusively by renewable energy sources. To become a zero carbon city, an established modern city must collectively reduce emissions of greenhouse gases to zero and all practices that emit greenhouse gases must cease. Also, renewable energy must supersede other non-renewable energy sources and become the sole source of energy, so a zero-carbon city is a renewable-energy-economy city. This transition which includes decarbonising electricity (increasing the importance of the sources of renewable electricity) and zero-emission transport, is undertaken as a response to climate change and peak oil.

Vehicles and other mobile machinery used for transport (over land, sea, air, rail) and for other uses (agricultural, mobile power generation, etc) contribute heavily to climate change and pollution, so zero emission engines are an area of active research. These technologies almost in all cases include an electric engine powered by an energy source compact enough to be installed in the vehicle. These sources include hydrogen fuel cells, batteries, supercapacitors, and flywheel energy storage devices. In some cases, such as compressed air engines, the engine may be mechanical rather than electrical. This mechanical engine is then powered by a passive energy source like compressed air, or a combustible non-polluting gas like hydrogen. The above engines can be used in all vehicles, from cars to boats to propeller airplanes. For boats, energy sources such as nuclear power and solar panels can also be a viable option, in addition to traditional sails and turbosails.
This study was conducted at Hisar and Karnal district of Haryana, India, to create awareness towards sequestration of greenhouse gases for sustainable agriculture. The 125 farmers were selected and interviewed with the help of well-structured schedule. The majority of the farmers were of middle age group (36-50 years), educated up to matric, belonged to a joint family (5-6 members), performed only farming and had average land holding up to 5 acres. The result shown that farmers' awareness towards greenhouse gases, climate change and global warming were found fully aware as per farmers' responses. Major causes of greenhouse gases were high use of inorganic farm inputs (2.88), intensive tillage practices (2.75) and etc. Very serious losses due to greenhouse gases were crop benefit ratio decreased, crop damaged due to adverse climatic uncertainty. Results pertaining adoption of alternative measures for sequestration of greenhouse gases for sustainable agriculture was medium. Farm practices like the evolution of new crop cultivars, crop diversification, zero tillage and integrated farming practices were found very effective among the farmers to reduce the greenhouse gases emission.
The earth is experiencing the adverse effect of climate change. In response to growing global warming issues and the constant increase of energy prices, house-builders and housing manufacturers today are becoming more responsive to the delivery of net zero energy and carbon dioxide emission sustainable homes than ever. Within this context, the sustainability may also embrace housing economy and adequacy beyond the legitimacy in which the quality barely coincides with individuals' dynamic various needs, desires and expectations. Nevertheless, the housing industry's business operation tends to follow routines and the close system mode of operation often hinders the enterprises from adopting unfamiliar innovations which may be inevitable in realising the delivery and operation of socially, economically and environmentally sustainable homes. This book showcases the zero energy mass custom home (ZEMCH) design workshop experience, which engaged with a wide spectrum of hopes and fears around the design, production and marketing approaches to low cost housing developments in Brazil.
It is possible to define zero energy/emission buildings by various aspects.Energy consumption in operation phase of the buildings is the majority discussion in this field.EU s targets regarding climate change and energy for sustainable growth which were approved by European parliament include greenhouse gas emission reduction by 20%,increase in consuming of renewable energy resources by 20% and achieving 20% increase in energy efficiency for moving toward zero energy/emission buildings until 2020.The zero energy/emission buildings are gaining interest as renewable energy resources which help to capture green house gases emission, especially CO2 emission.By considering this fact that residential buildings consume 40% of total delivered energy in Sweden,the scientifically assessment of CO2 level in this country by residential sector on one hand and implementing new technologies for decreasing GHG emission in term of decreasing energy consumption on the other hand are very important. By knowing this fact that for producing 1KWh energy in Sweden around 40g CO2 emission is released,in two million Swedish single family houses it is possible to capture around 800000 tonnes CO2 emission
BIOFUEL SUSTAINABILITY: There has been a higher decline in the easily available fossil fuels and as well, with their availability, there is serious concern about the carbon dioxide and nitrogen dioxide emissions any time such fuels are burnt. Carbon dioxide poses serious threat to the atmospheric environment and can lead to global warming and, nitrogen dioxide emission can lead to acidic rain which is detrimental to the natural environment and can as well involve in stratospheric ozone reactions and lead to climate change. Biomass is indeed considered as the most promising resource since it is very abundant and sustainable. Biomass can therefore be used to produce environmental friendly liquid fuel via a number of technological processes such as pyrolysis. Biomass derived fuels when burnt produces zero or negative carbon dioxide emissions due to the fact that the plants utilizes carbon dioxide during the photosynthesis process. This book therefore outlines the steps involved in producing clean green transport fuel from biomass(wood pellets) by pyrolysis and how the pyrolysis oil is upgraded via catalytic hydrothermal treatment.
The book discusses the aspects of energy use in buildings, several energy conservation opportunities in the existing buildings, use of renewable energy systems, use of passive solar heating and cooling techniques, bio-climatic buildings, green buildings and zero-emission buildings so as to conserve electricity. The effort being undertaken by various State Government and the Central Government under the National Action Plan on Climate Change may go a long way in providing sustainable habitat to fight the menace of climate change.
The UN Climate Change Conference in Paris, with its key topics of global warming and deteriorating air quality, will speed up the advance of electric mobility. CO2-neutral and zero-emission mobility require electricity to be generated from regenerative sources of energy. Power generation from wind and solar energy, however is dependent on the weather and is therefore not stable. The irregularities that occur in nature can result in unacceptable voltage fluctuations in the power grid. For that reason, the availability of highly flexible loads and storage systems is becoming particularly important. Electric vehicles, with their grid-relevant properties as controllable power consumers and electricity storage systems, could help to stabilize future power grids.
Hydrogen is believed to be the energy source of the future, enabling zero-emission and efficient production of power. This comprehensive publication presents a broad spectrum of various chemical aspects of hydrogen storage. The authors also address global climate change issues, carbon dioxide sequestration problems and CO2-based hydrogen storage.
