(continued, page 4) (continued, page 2) Ask the average person where electricity comes from, and he or she is likely to reply, “Out of a wall socket.” Pressed further, they may suggest a thermal or hydroelectric plant as the source, depending on where they live in the country. In response to further probing, some may guess either nuclear power or fossil fuel as the origin. But it would be only ...

The study presents a cost effective electricity generation portfolio for six island states for a 20-year period (2015–2035). The underlying concept investigates whether adding sizeable power capacities of renewable energy sources (RES) options could decrease the overall costs and contribute to a more sustainable, indigenous electricity generation at the same time. Often, island states rely on f...

Fossil fuels will have large impacts on ocean chemistry and climate during the period while they are being burnt (and carbon dioxide emitted) in large amounts. It is frequently assumed that these impacts will fade away soon thereafter. Recent model results, by contrast, suggest that significant impacts will persist for hundreds of thousands of years after emissions cease. We present a new analy...

The international divest–invest movement, which has been gaining momentum since ...

Due to Iceland’s location on the Mid-Atlantic ridge, the island is provided with a great amount of geothermal energy. Hence, Iceland is well on the way to becoming completely independent of fossil fuels. Whereas high-temperature areas are mainly used for electricity generation, the more frequent low-temperature areas are utilized for direct application like space heating, bathing and greenhouse...

● Global reserves of coal, oil and natural gas are diminishing; global energy requirements however are dramatically increasing. Renewable energy sources lower the threat to the earth’s climate but are not able to meet the energy consumption in major urban areas. The opinion of many experts is that the future will be dominated by hydrogen. However, this gas is essentially totally manufactured fr...

The world needs new, environmentally friendly, and renewable fuels to exchange for fossil fuels. The fuel must be made from cheap, abundant, and renewable resources. The research area of solar fuels aims to meet this demand. This paper discusses why we need a solar fuel, and proposes solar energy as the major renewable energy source to feed from. The scientific field concerning artificial photo...

Most bituminous adhesives or binders that are used for pavement materials are derived primarily from fossil fuels. With petroleum oil reserves becoming depleted and the drive to establish a bio-based economy, there is a push to produce binders from alternative sources, particularly from biorenewable resources. However, until now, no research has studied the applicability of utilizing bio-oils a...

Improving Operational Efficiency Through the Use of Smart MCCs in Process Automation Systems Executive Summary The escalating price of fossil fuels marked by fierce global competition is driving process industry decision makers to rethink the way their businesses will perform in the future. In order to stay competitive, manufacturers will have to develop strategies to conserve energy and limit ...
