Psychology Energy drinks and Drug use Now days‚ college students have been consuming the so-called “energy drinks‚” a rapidly evolving class of drink which promise to increase energy‚ improve alertness‚ and boost attention. Energy drinks started around the 1990s‚ the industry has grown with a rate of 55% from 2002 to 2006. Energy drinks are marketed usually to young adults. A few studies have attempted to identify the influences of energy drink drinking‚ drug use‚ and alcohol forms of use

Work Renewable and Non-renewable energy sources &Fuels: Renewable energy comes from natural sources that are constantly and sustainably replenished. The most common renewable energy sources are biomass‚ hydroelectric‚ geothermal‚ wind power and solar power. Sunlight is the source of most renewable energy power; the sun can be used to produce solar energy which is electricity for heating‚ cooling‚ lighting homes and transportation.

Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

mysterious dark energy that’s causing the expansion of the universe to accelerate? Is it some form of Einstein’s famous cosmological constant‚ or is it an exotic repulsive force‚ dubbed "quintessence‚" that could make up as much as three-quarters of the cosmos? Scientists from Lawrence Berkeley National Laboratory (Berkeley Lab) and Dartmouth College believe there is a way to find out. | | | | The SuperNova/Acceleration Probe‚ SNAP‚ is a satellite designed to study dark energy through the discovery

Geothermal Energy Introduction The Geothermal is a clean and sustainable (renewable) energy. It has been estimated that the heat of the centre of the earth may reach 6000°C. It has been found that the increases one degree °C for 30-50 meters. The word geothermal is derived from Greek language where the first syllable “Geo” means “earth” and the second syllable “thermal” means “heat”. How it works The geothermal energy should be made useful through electrical generators. We are not free to dig
