In energy conservation and energy economics, the rebound effect (or take-back effect) is the reduction in expected gains from new technologies that increase the efficiency of resource use, because of behavioral or other systemic responses. These responses diminish the beneficial effects of the new technology or other measures taken.

The world share of energy production in Africa was 12% of oil and 7% of gas in 2009. [8] This map shows a snapshot of fossil fuel resources and renewable energy projects across Africa. Percentage of total energy use in Africa by country (2009)
A reverberation chamber is used to test the sound absorption coefficients and NRC of a material. The noise reduction coefficient (commonly abbreviated NRC) is a single number value ranging from 0.0 to 1.0 that describes the average sound absorption performance of a material. An NRC of 0.0 indicates the object does not attenuate mid-frequency ...
A proposed dam on the Congo River, which drains much of western Africa and is one of the world’s largest waterways, illustrates the promise and peril of massive infrastructure investment. Last year, the World Bank approved a $73 million grant to help the Congolese government study the dam’s environmental and social impact.
World consumption of primary energy by energy type. [1] Energy consumption per capita per country (2001). Red hues indicate increase, green hues decrease of consumption during the 1990s. [2] The environmental impact of the energy industry is significant, as energy and natural resource consumption are closely related.
Montrell Johnson Jr.'s 5-yard touchdown run with 7:40 remaining in the fourth quarter gave Florida a 24-17 win over No. 9 Ole Miss on Saturday in Gainesville. Ole Miss had a chance to tie the game ...
