Energy Guide for kids What are fuels? How do you get energy from them? Now this is where humans are different from all other life. What A Way To Go: Life at the end of Empire Tim Bennett, middle-class white guy, started waking up to the global environmental nightmare in the mid-1980s. But life was so busy with raising kids and pursuing the American dream that he never got around to acting on his concerns. Until now… Bennett journeys from complacency to consciousness in his feature-length documentary, What a Way To Go: Life at the End of Empire. He reviews his Midwestern roots, ruthlessly examines the stories he was raised with, and then details the grim realities humans now face: escalating climate change, resource shortages, degraded ecosystems, an exploding global population and teetering global economies. Bennett identifies and calls into question the fundamental assumption that has led to this unprecedented crisis in human history: that humans were destined to dominate the rest of the community of life with the Culture of Empire.
Video reveals how much social media reveals about you to strangers We’ve been told. And told and told and told: Social networking is not private, the Internet doesn’t forget, and apps can do nearly anything they want with our data. But despite the many warnings, we’re consistently still surprised by how much our digital profiles reveal. Social Media Experiment, a YouTube video created by YouTuber Jack Vale, makes it as undeniable as ever how oblivious we are. Electricity for kids - and everyone else: A simple introduction! Advertisement by Chris Woodford. Last updated: April 14, 2016. If you've ever sat watching a thunderstorm, with mighty lightning bolts darting down from the sky, you'll have some idea of the power of electricity. A bolt of lightning is a sudden, massive surge of electricity between the sky and the ground beneath. The energy in a single lightning bolt is enough to light 100 powerful lamps for a whole day or to make a couple of hundred thousand slices of toast!

The IEA has updated estimates since 2009, but the overall trends are the same. We hope that with the implementation of demand-side efficiency measures worldwide, long-range estimates will prove to be overestimated. According to the US Department of Energy (Energy Information Administration), the world consumption of energy in all of its forms (barrels of petroleum, cubic meters of natural gas, watts of hydro power, etc.) is projected to reach 678 quadrillion Btu (or 715 exajoules) by 2030 – a 44% increase over 2008 levels (levels for 1980 were 283 quadrillion Btu and we stand at around 500 quadrillion Btu today in 2009).
How do solar panels work? - Science Questions A solar panel turns the sun’s light into electricity! We see electricity at work every day. For instance, when you turn on a lamp, electrons move through the cord and light up the bulb. That flow of electrons is called electricity. One solar panel is made up of many small solar cells. BOOK REVIEW: 'Clean Energy Nation': The Facts on the End of Petro-Civilization As We Know It (The wimpy storm made landfall at Baffin Bay, about 40 miles south of Corpus Christi, TX, late Friday night and then fizzled: Link: Maybe Don was angry at the storm-namers who didn't name him "Donaldo," or "The Donald," because his arrival left only a trace of rain, just enough to remove the dust on my PT Cruiser. I've long been a semi-believer in climate change, blaming most of it on the People's Republic of China, by far the world's biggest polluter of air and water (for more about that see my upcoming review of a book called "Death by China") , but I'm told conservative Texans would dispute the loud and clear message on climate change presented in "Clean Energy Nation: Freeing America from the Tyranny of Fossil Fuels" (Amacom (American Management Association), 320 pages, $27.95) by Congressman Jerry McNerney, Ph.D, and Martin Cheek.
40 Maps That Will Help You Make Sense of the World If you’re a visual learner like myself, then you know maps, charts and infographics can really help bring data and information to life. Maps can make a point resonate with readers and this collection aims to do just that. Hopefully some of these maps will surprise you and you’ll learn something new. Causes of extinction Trilobite fossil dating to the early Edenic Period. Source: C.Michael Hogan fossil collection Causes of extinction have prehistorically been dominated by natural earth processes such as geological transformation of the Earth's crust and major climatic oscillations, as well as species interactions; however, since the ascent of modern man during the Holocene, the causes of extinction have been dominated by the activities of humans. Rates of species extinction have increased rapidly since the early Holocene epoch, chiefly due to activities of humans; further acceleration of extinction rates began approximately 1600 AD, with the onset of accelerated human population growth and expanded scope of agriculture. Natural causes of extinction are regarded as being an irrelevantly small fraction of present extinction events, but are important to understand for historical and academic context. Since prehistoric times, humans have used the earth’s resources to enrich their own lives.
Solar Energy 101 - Green Mountain Energy Company About Solar Energy Solar energy is generated using the sun’s powerful rays. Because sunlight is inexhaustible, solar energy is a valuable renewable energy source – capable of directly generating heat, light and electricity.
