Just some of the consequences that can be reasonably expected are rising sea levels, more frequent and more severe natural disasters, large-scale food and water shortages, plagues, massive species extinctions, unprecendented numbers of refugees, intensified ethnic and political tensions, and a global economic depression the likes of which no one has ever seen.

Electricity -- the flow of electrical power -- is a secondary energy source, generated by the conversion of primary sources of energy, like fossil, nuclear, wind or solar.

Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system

How to destroy the Earth @ Things Of Interest
In the last minutes, stars and planets will come apart, and atoms will be destroyed a fraction of a second before the end of time." Cool, eh? Earth's final resting place: HAH! If I knew that, I wouldn't need aftershave. The concept is simple: find a really, really big asteroid or planet, accelerate it up to some dazzling speed, and smash it into Earth, preferably head-on but whatever you can manage
EARTH HOUR
While the global lights out remains an impactful visual call-out, its true impact is starting to be seen in areas and communities fighting climate change on an everyday basis
http://www.amazon.com/Planet-Earth-The-Complete-Series/dp/B000MR9D5EWe love the narration by David Attenborough because his voice is soothing and very articulate and allows you to enjoy the episodes without taking anything away from the experience. This series is packed full of episodes ranging from Mountains to Deserts to Shallow Seas to Ocean Deep, with so much more! It's easy enough to watch one episode at a time and come back to the DVD without missing anything or feeling like you have forgotten what happened in the last episode because they are all separate subjects
Encyclopedia of Earth
Unlike the surrounding woodlands that generally support animals only in rather low densities, the wetlands and floodplains of this ecoregion provide habitats to sizable faunal populations, since food and water are abundant throughout the majority of the year. Herbivores can vary greatly in size, ranging from the largest terrestrial animals (elephants) and large marine mammals such as manatees and dugongs, to small insects, nematodes, and thrips
The Energy Story - Chapter 2: What Is Electricity?
The Latin word, electricus, means to "produce from amber by friction." So, we get our English word electricity from Greek and Latin words that were about amber. But what is electricity? Where does it come from? How does it work? Before we understand all that, we need to know a little bit about atoms and their structure

Common Creationist Criticisms of Mainstream Dating Methods Most creationist criticisms of radiometric dating can be categorized into a few groups. "meteoritic material" Some folks in talk.origins occasionally sow further confusion by discussing the thickness of the "lunar soil" as if it represented the entire quantity of meteoritic material on the lunar surface

The Energy Story - Introduction
The forms of energy we will look at include: Electricity Biomass Energy - energy from plants Geothermal Energy Fossil Fuels - Coal, Oil and Natural Gas Hydro Power and Ocean Energy Nuclear Energy Solar Energy Wind Energy Transportation Energy We will also look at turbines and generators, at what electricity is, how energy is sent to users, and how we can decrease or conserve the energy we use
