Renewable Energy Is Capable of Meeting Our Energy Needs Despite having public support and advantages over other energy sources‚ renewable technologies have been repeatedly characterized as unable to meet our energy needs. People have been presented only a choice between conventional fossil fuels and nuclear power. This‚ however‚ is a false choice. Renewable energy can reliably generate as much energy as conventional fuels‚ and can do so without producing carbon emissions or radioactive waste

It can begin simply by turning off a light switch as someone leaves a room or unplugging a device when not in use. From these small acts‚ the beginning seeds of energy conservation can be sown. Energy conservation has become one of the most hotly debated subjects in the world. Old power plants are struggling to keep up‚ sometimes causing power shortages or “brown outs”‚ and new power plants are being built‚ but most of the new plants still use the same technology as their predecessors. Some

Forms of Energy CHEMICAL Energy Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed – chemical reactions. Chemical reactions change the way atoms are arranged. NUCLEAR Energy Nuclear energy is the stored potential of the nucleus‚ or center‚ of an individual atom. Most atoms are stable on Earth; they retain their identities as particular elements‚ like hydrogen‚ helium‚ iron‚ and carbon‚ as identified

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
