Renewable energy technologies׳ systems are major components of the strategy to reduce harmful emissions and deal with depleting energy resources. It is necessary to deploy renewable energy sources in the best possible way such that cost is minimized and generation is maximized. In this paper,...

The objective of this research is to analyze the effectiveness of wind power and solar energy to supply electricity to the grid during peak demand periods in the Northeast of Brazil. To achieve this objective, a comparative analysis is performed between the electricity load curve for a typical...

The benefits of promoting renewable energy are regularly claimed to be energy security, climate change mitigation and job creation. While the first two benefits are generally accepted, the impact of renewable energy on employment is still disputed. This paper presents a discussion of the various...

Energy is essential to life and human society cannot surviva without a continuous supply of energy. However, although energy has brought about significant changes in standards and life-styles, its generation, processing and consumption is also a source of both localized pollution and a major...

With policy encouragement and capital investments, China's wind power has been enjoying a tremendous development for years. China has now become a global leader in terms of wind power capacity, with a total of 52.58 gigawatts of wind power connected to power grid. However, the overwhelming...

A system integrating CHP (combined heating and power) subsystem based on natural gas and GSHP (ground-source heat pump subsystem) in series is proposed. By help of simulation software-Aspen Plus, the energy performance of a typical CHP&GSHP-S (S refers to ‘in series’) system was analyzed....

Currently, several renewable energy technologies have reached, or are approaching maturity and can be utilised for small- and large-scale applications. Biodiesel, a cleaner burning replacement fuel, is argued to potentially contribute to sustainable development in many countries and regions of...

With increasing renewable energy targets and the use of biomass for energy production, questions arise about the sustainability of differing types of bioenergy. Much has been made about the renewable transport fuel obligations and the impact the production of biofuel can have on the...

This paper first provides an overview of the context of renewable energy development in China, including the country's recent renewable energy legislation. Further, it summarizes the current status of renewable energy development and the role it plays in the national energy supply. Next it...

The objective of this study is to examine the potential for a full transition to domestically produced biofuels in the Stockholm County transport system in 2030, without exceeding the proportional share of national bioenergy assets. This target is chosen in order to test the potential of biofuel...
