Those photons are hauling and when they strike your PV module you can convert that motion to electricity. In that 8 minutes it traveled 93 million miles. The light falling on your face left the Sun just 8 minutes go. Mankind has been crazy to have not bothered to harness the sun's energy until now. With solar, there's no acid rain, no urban smog, no pollution of any kind. The same solar system will also prevent the need to burn 60,000 pounds of coal. A 1.5 kilowatt PV system will keep more than 110,000 pounds of carbon dioxide, the chief greenhouse gas, out of the atmosphere over the next 25 years. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy sources.В Combined with the use of recycling, the use of clean alternative energies such as the home use of solar power systems will help ensure man's survival into the 21st century and beyond.ДЇrom an environmental perspective, solar power is the best thing going. They all have lower carbon emissions, compared to conventional energy sources. Alternative energy sources are renewable and are thought to be 'free' energy sources. Climate change, population growth, and fossil fuel depletion mean that renewables will need to play a bigger role in the future than they do today.ДЄlternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Who says? British Petroleum and Royal Dutch Shell, two of the world's largest oil companies. We call this Alternate energyД«y 2050, one-third of the world's energy will need to come from solar, wind, and other renewable resources. One answer to global warming is to replace and retrofit current technologies with alternatives that have comparable or better performance, but do not emit carbon dioxide. This increased content of Carbon Dioxide increases the warmth of our planet and is the main cause of the so called вЂњGlobal Warming EffectвЂќ. Wind PowerД®veryday, the world produces carbon dioxide that is released to the earthвЂ™s atmosphere and which will still be there in one hundred years time. From photovoltaic (PV) cells that capture photons and convert them into electricity, to solar thermal energy (STE) that makes use of the sunвЂ™s heat, solar is one of the most promising alternative energy sources on the market today. What better way is there to reach Type I status, than to get your energy straight from the source-solar power involves harnessing the power of our sun. At we aim to cover solar, wind, biomass, hydroelectric power, geothermal and other carbon neutral energy sources that will help humanity transition to a sustainable future. Renewable energy sources that donвЂ™t produce carbon dioxide emissions and other greenhouse gasses that contribute to anthropogenic climate change. While weвЂ™ve got a shot at Type 1, the adverse effects of burning fossil fuels have left us in dire need of an alternative.Д®nter, alternative energy - any energy source that provides an alternative to the status quo. By the dawn of the Industrial Revolution (mid 1700s), fossil fuels had fueled the rapid advancement and expansion of human civilization, reaching a population of 1 billion by 1800.Д¬ontemporary society currently rests at 0.73 on the Kardashev scale. At the dawn of the first millennium AD, global population was a mere 150-200 million people, reaching 300 million by the year 1000 AD. In many ways energy is the currency of our Universe, from single celled organisms swimming in primordial pools, to colonies of Meerkats on the African savannah, to sprawling metropolises like New York, Sydney, or Beijing. When renown astrophysicist Nikolai Kardashev first set out to measure a civilizationвЂ™s level of technological advancement in 1964, he settled on energy consumption as the best metric for gaging progress on a cosmic scale. Alternative Energy Altenergy IntroductionДЎ0В№вЃ¶ watts - thatвЂ™s roughly the amount of energy at the disposal of a civilization that can harness all the incident solar radiation that falls on a planet from its parent star - Type I on the Kardashev scale.
