Following the recent completion of three nuclear power plants, there is now some 9.6 GW of nuclear capacity in the United Kingdom. The nuclear share of electrical output, which has stood at around 13% for many years, should rise to around 20% when this capacity is in full operation. A further two reactors are currently under construction which will increase the British nuclear capacity to more than 12 GW by the late 1980s, which could bring the nuclear share of electrical output to around 25%.

Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)

Addressing global warming, however, is a highly complex and daunting endeavor. Many climate experts have urged the world to stabilize greenhouse gas concentrations in the atmosphere around 450 to 550 parts per million (ppm)—that is, no more than 450 to 550 units of greenhouse gases for every million units of air in the earth’s atmosphere. This approach, experts say, could keep average global temperatures at no more than 3.6° Fahrenheit (2° Celsius) above preindustrial levels, which could avoid some of the worst, irreversible consequences of climate change.

There are various and somewhat complementary reasons to foster the growth of renewable energy sources in Europe. A major incentive for renewable energy sources policies in the past two decades has been to reduce the environmental impact of energy use both locally (e.g., pollutant emission reduction) and globally (e.g., greenhouse gas and carbon emissions reduction). In some countries, concerns about the safety of nuclear power generation have motivated the search for renewable energy sources. Another motivation for replacing foreign fossil and nuclear fuels with domestic renewable energy sources relates to security issues and Europe’s growing dependency on foreign energy sources. (more…)

Nuclear energy has some distinct advantages in strengthening the external dimension of energy supply security. These include:
• Nuclear power plants produce electricity domestically. Their capital and labor inputs are also provided domestically. With more than 90% of its inputs in terms of value sourced domestically, it can be considered a largely domestic source of energy and electricity.
• Of course, a majority of OECD countries import part or all of their requirements of uranium plutonium. (more…)

It shows Well-to-Wheels Greenhouse Gas emissions of the 23 vehicle/fuel systems. For each system, the bottom bar represents CO2 -equivalent emissions of CO2 , CH4 , and N2O, combined with their greenhouse global warming potentials (GWPs). The top bar represents CO2 emissions only. For the two ethanol pathways (corn and cellulosic ethanol), there are some negative emissions. They represent carbon uptake during biomass growth. The carbon is eventually emitted to the air during ethanol combustion air. (more…)

In recent years, there has been a greater understanding of the role of automotive emissions as environmental pollutants. Sulfur dioxide, nitrogen oxides, and carbon monoxide degrade the earth’s atmosphere and are health hazards. Carbon dioxide adds to the atmospheric buildup of greenhouse gases and in turn accelerates the process of global warming. (more…)
