UK Energy Demand: The United Kingdom Trends in Energy

uk energy demand
The long-term prospects for the U.K. economy are inevitably uncertain, and the most recent Department of Energy long-term projection puts forward three scenarios for the next 30 years with GDP growth rates of roughly 2.5, 1.5 and 0.5% p.a. The highest value corresponds to slightly less than the 1948 - 72 average, the central value is close to the long-run average over the last 80 years, and the lowest figure is similar to the performance during the current recession since 1973.

Energy Quality and Shifts in Composition of Energy Input

Energy quality is the relative economic usefulness per heat equivalent unit of different fuels and electricity. One way of measuring energy quality is the marginal product of the fuel, which is the marginal increase in the quantity of a good or service produced by the use of one additional heat unit of fuel. These services also include services received directly from energy by consumers. Some fuels can be used for a larger number of activities and/or for more valuable activities. For example, coal cannot be used directly to power a computer whereas electricity can. The marginal product of a fuel is determined in part by a complex set of attributes unique to each fuel: physical scarcity, capacity to do useful work, energy density, cleanliness, amenability to storage, safety, flexibility of use, cost of conversion, and so on. But also the marginal product is not uniquely fixed by these attributes. (more…)

Modern Coal Plants – Efficient & Lower Emissions Power Plants

Coal Power Plants
Coal use today is no longer evocative of dirty power plants with polluting black smoke billowing from their smokestacks. Many of these plants have been transformed through technology to operate more efficiently and with significantly lower emissions. Some fire coal with other waste materials and others produce both electric power and heat transmission. Cases of plant retrofits and their new performance statistics are documented by various institutions, including the Energy Information Administration (http:// www.eia.doe.gov) and the World Coal Institute (http://www.wci-coal.com). The following examples highlight clean coal use throughout the world: (more…)

Coal Use for Electricity Generation Power

Coal Electricity Generation
The largest use of coal today is in the generation of electric power by electric utilities. According to the U.S. Energy Information Administration, about 65% of coal mined in the world is used for power generation. The next largest use of coal is in the production of coke for the iron and steel industries. Coal is still used for industrial heating and even commercial heating and residential heating in certain countries. (more…)

Biomass Gasification: Electricty Conversion from Feedstock

Biomass Gasification
Gasification is a thermo chemical process that has been exploited for more than a century for converting solid feedstocks to gaseous energy carriers. The first gasifier patent was issued in England at the end of the 18th century and producer gas from coal gasification was mainly used as lighting fuel throughout the 19th century. At the turn of the 20th century, the main use of producer gas, obtained essentially from coal, switched to electricity generation and automotive applications via internal combustion engines. The use of producer gas was gradually supplanted by the use of higher energy density liquid fuels and as a result confined to areas with expensive or unreliable supplies of petroleum fuels. (more…)

Oil Trading and Tanker Transportation

Tanker transportation and oil transport functions as an important link to facilitate the flow of oil and products from their limited sources of origin derived to its destination all over the world. This particular section of ocean shipping industry is the main component of the movement of seaborne cargo. Even though oil is transported through pipelines and tankers and tank wagons, these movements are relatively small and often restricted to national or in a few cases trough the intra-regional trades. The increment in oil demand came not only from the United States & Western Europe, however there is a rapid oil demand recovery in Japan, a country with no domestic oil reserves. (more…)

Economics Value of Energy

We have seen that energy is basic for life and activities in nature and society. Energy is a measure of value in physical terms. However, the more complex a system or a process becomes, the less can be said by physics. Even the term ‘‘complexity’’ is problematic. There are several definitions of complexity as a quantitative concept in information theory. (more…)

Energy Import Dependence, Resource Exhaustion and Carbon Policy

energy import dependence
Geopolitical risk refers almost always to primary energy carriers (oil, gas, coal, uranium or renewable energy) since their location depends on the vagaries of geology and climate. Production and energy consumption are thus often physically far apart and take place in countries and regions with different histories, cultures and values. Apart from oil & gas exploration and production, all other steps of the energy chain such as refinement or enrichment, energy conversion and distribution can be moved physically closer to the final customer or are, like consumption, directly under the latter’s control.

CO2 Capture and Hydrogen Production Plan by ELCOGAS

The pilot plant for carbon dioxide capture and hydrogen production using combined cycle ELCOGAS Puertollano “will be the first in the world is put into operation next March.”

There is another similar initiative, CO2 capture in a power of the same technology, Buggenum (Netherlands), but construction is delayed by six months regarding the central of Puertollano, according to the company ELCOGAS in a press release. (more…)

Climate Impacts on Energy Demand

Energy is consumed by various segments of the economy, including households, commercial establishments, manufacturing enterprises, and electric power generators. Only a portion of total energy demand is sensitive to temperature changes. (more…)
