In the current energy landscape, utilities play an important role in promoting energy efficiency. The 2023 Energy Survey underscores the utilities' proactive responses to market demands for sustainability and cost-effectiveness in energy efficiency services. ...
History of Development As early as 1985, the discovery of fullerene with the “football” structure immediately attracted the world’s attention. Then, carbon nanotubes with a hollow cylindrical structure are formed based on mild modifications toward fullerenes. In 1991, Japanese researchers discovered carbon nanotubes in carbon fibers for the first time. In 2004, researchers ...
Centre Dufferin District High School Size: 50 kW (20 kW facade, 30 kW flat roof) HELIENE Modules: 200 – HELIENE 60M 250Wp Modules The Upper Grand District School Board is committed to promoting and teaching environmental stewardship and the Centre Dufferin District High School in Shelburne is a leader in demonstrating energy conservation and ...
At present, the main ways of municipal solid waste (MSW) treatment are landfill, composting, incineration, and so on. But these treatments still require a lot of lands. RDF preparation technology has obvious advantages in environmental protection and resource utilization, and will be better developed in the future. It brings vitality to waste energy and becomes a new growth point in the field of ...
The remedy in the energy sector is customer-sited renewable generation and storage technologies that create critical reserves and the ability to generate, store and utilize power independent of the utility grid. ...
Senate aide in the 1970’s and ran the Solar Energy Industries Association (SEIA) in the 1980’s and 1990’s, I would constantly face the lament by oil state Democrats and corporate Republicans indignantly whining about federal and state government subsidies for energy efficiency and renewable energy. ...
On an annual basis, the Department of Energy approximated power outages cost the U.S. economy a whopping $150 billion. ...
The technology is extremely flexible and scalable: It can process a variety of source feedstocks, generate multiple forms of energy and useful byproducts and deliver efficient power generating performance (35% or more efficiency) in a range of applications and industries. ...
Hydrogen is a renewable energy source and has the potential to mitigate the green house gas effect and to meet the increasing global electricity demand. In the present study, a multicriteria methodology is developed by combining graph theory and analytic hierarchy process methods for the evaluation and selection of hydrogen energy systems. The hydrogen energy system alternatives are assessed ...
Under the prevailing conditions, ethanol production from sugar beet shows to be reasonably energy efficient. A net energy production has been calculated of 32 and 37 GJ/ha. Crop and ethanol yields are above those reported elsewhere, as is the energy use per hectare which is related to crop yield. Applying ...
This paper attempts to grasp the direction in current and previous published articles in alternative energy adoption literature with a concentration on methods, perspectives, approaches and technologies that have been subject to research. Findings imply that alternative energy technology adoption literature has diversified into various research perspectives which are named in our study as: ...
Four years after the US credit market crashed, energy efficiency projects continue to struggle to secure financing. What’s the problem? A slow economy, of course. But when it comes to energy efficiency – and on-site renewable energy – the problem runs deeper. It’s not lack of interest in green energy. To the contrary, says Angela Ferrante, director of alternative energy ...
An investigation under which conditions industrial waste heat utilised with magnetic energy conversion machines can be a possible alternative to conventional energy conversion technologies is presented. The application of a numerical model leads to the thermodynamic efficiency, the exergy ...
Renewable energy is a viable option for electrical power in developing and emerging nations. In most of these nations, there is a huge demand for energy that far exceeds what the countries are currently able to generate. While some nations are exploring renewable and alternative energy to reduce the impact their energy consumption has on the environment, others are still seeking avenues to boost ...
Rapidly depleting conventional petroleum resources have prompted research for alternative fuels. Among various possible options for internal combustion engines, fuels derived from triglycerides (vegetable oils/animal fats) are a promising substitute for diesel fuel. Vegetable oils pose some detrimental characteristics like high viscosity and low volatility compared to diesel fuel. In the present ...
The problem for the US is that its goals for energy efficiency are more closely aligned with reducing dependence on foreign energy sources such as fossil fuels rather than becoming the dominant developer of energy efficient technologies. ...
This paper discusses the merits and limits of the recent European energy policy aimed at reducing carbon emissions, devoting particular attention to the European trading system of carbon permits and to the measures that the European Union has adopted to promote renewable energy sources. From the comparison of past goals and present results, it is argued that more credible targets for carbon ...
Greenhouse gas reduction occurs as a result of substitution of woody biomass for coal. Coal is the worst amongst all the fossil fuels in terms of greenhouse gas emission per unit of electricity generated. Recent concerns related to the environmental impact of greenhouse gases from using fossil based feedstock, like coal, for the generation of power, specifically electricity have driven the need ...
Rapid growth in Iran's domestic energy demand and its dependence on oil exports for revenue has forced it to consider alternative future energy solutions. Years of inadequate investment in new infrastructure to develop oil and gas reserves may lead to a rapid decline in oil production and delays to key projects that have the potential to expand oil and gas exports over the next decade. Broad ...
Global energy model GEM-10R has been used to analyse the possible conditions and scale of using space and terrestrial solar power plants in the long-term perspective (up to the end of the 21st century). Different external conditions, when these alternative energy technologies may be feasible, have been revealed and discussed.Keywords: global energy model, space-based power systems, lunar power ...
