Energy sources in the world impact the environment, including climate change and global gas emissions, which lead to the development of renewable energy sources. This paper investigates gym equipment as an energy-generation approach to support energy consumption or utilization for a building listed as Net-Zero Energy Building. This alternative method to generate energy sources is based on two gym equipment, i.e., a static bicycle and a treadmill. The mechanical energy will be transformed into electrical energy from an alternator before storing it in a battery. Then, an inverter circuit was designed to convert the DC to AC to power the electrical appliances. Several analyses have been made, including the durability and improvement strategies for the system's stability. Overall, this system has achieved its objectives and generates sufficient energy for a building. This concept is an innovation for power harvesting that appears to generate a renewable energy source and can be applied to any building, primarily in residential areas. [ABSTRACT FROM AUTHOR]

Freezer and refrigeration plants are among the highest consumers of electric energy because they must provide sufficient cooling capacity. At present, the technical standard for design, the European document for the technical approval of EOTA and the recommendations of refrigeration and logistics associations have to be applied to this area in the conditions of the Czech Republic. The recommendations focus on efficient energy consumption, targeting energy fuels, reducing CO2 emissions, which helps to suppress global warming as a result of climate change. The paper demonstrates the degree of energy savings by numerical modeling due to the shielding of solar radiation acting on the perimeter cladding by structural modification of the outer overhanging façade with a ventilated air layer.

Climate change has been a global challenge which researchers have been trying to curtail over the years using different scientific approach, a major contributor to climate change is the combustion of fossil fuel which has influenced the search for alternative fuel sources among which is biodiesel. However, Biodiesel is associated with its limitations including higher nitrogen oxide (NOx) emission. This paper therefore present various recent findings and impacts of blending nanoparticles with biodiesel and conventional diesel, the merits and demerits in terms of power output, fuel consumption and emissions as well as the possibility of using nanofluids as future alternative fuel for diesel and gasoline engines.

The Low Carbon Land Transport criteria sets out what transport projects are applicable for certification under the Climate Bonds Standard. Projects are determined eligible if they are compatible with an emission trajectory that limits global temperature rise. In this paper, the existing research on energy consumption during 2005 to 2009 in Nanjing was carried out to analyze its carbon dioxide emission characteristics. [ABSTRACT FROM AUTHOR]

Smart grid and distributed generation should be the solution of the global climate change and the crisis energy of the main source of electrical power generation which is fossil fuel. In order to meet the rising electrical power demand and increasing service quality demands, as well as reduce pollution, the existing power grid infrastructure should be developed into a smart grid and distributed power generation which provide a great opportunity to address issues related to energy efficiency, energy security, power quality and aging infrastructure systems. The conventional of the existing distributed generation system is an AC grid while for a renewable resources requires a DC grid system. This paper explores the model of smart DC grid by introducing a model of smart DC grid with the stable power generation give a minimal and compressed circuitry that can be implemented very cost-effectively with simple components. The PC based application software for controlling was developed to show the condition of the grid and to control the grid become 'smart'. The model is then subjected to a severe system perturbation, such as incremental change in loads to test the performance of the system again stability. It is concluded that the system able to detect and controlled the voltage stability which indicating the ability of power system to maintain steady voltage within permissible rangers in normal condition.

Climate change due to carbon dioxide (CO2) emissions is one of the most complex challenges threatening our planet. This issue considered as a great and international concern that primary attributed from different fossil fuels. In this paper, regression model is used for analyzing the causal relationship among CO2 emissions based on the energy consumption in Malaysia using time series data for the period of 1980-2010. The equations were developed using regression model based on the eight major sources that contribute to the CO2 emissions such as non energy, Liquefied Petroleum Gas (LPG), diesel, kerosene, refinery gas, Aviation Turbine Fuel (ATF) and Aviation Gasoline (AV Gas), fuel oil and motor petrol. The related data partly used for predict the regression model (1980-2000) and partly used for validate the regression model (2001-2010). The results of the prediction model with the measured data showed a high correlation coefficient (R²=0.9544), indicating the model's accuracy and efficiency. These results are accurate and can be used in early warning of the population to comply with air quality standards. [ABSTRACT FROM AUTHOR]
