An energy-efficient heating and cooling alternative, the geothermal heat pump system moves heat from the ground to a building (or from a building to the ground) through a series of flexible pipe "loops" containing water. This edition of Energy 101 explores the benefits Geothermal and the science behind how it all comes together.

Iceland is leading the way when it comes to using magma as an alternative source of fuel. In fact, they even came up with the first ever geothermal plant after accidentally drilling into magma back in 2009! Trace explains how this new power plant is changing how we heat our homes in hopes for a more sustainable future. Read More: How Geothermal Energy Works http://science.howstuffworks.com/environmental/energy/geothermal-energy.htm "We depend on our cars to take us to work and get our children to school. We rely on our home heating systems to keep us warm in the winter. We take it for granted that we could easily switch on our computer, vacuum cleaner or oven." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

A home energy checkup helps owners determine where their house is losing energy and money - and how such problems can be corrected to make the home more energy efficient. A professional technician - often called an energy auditor - can give your home a checkup. You can also do some of the steps yourself. Items shown here include checking for leaks, examining insulation, inspecting the furnace and ductwork, performing a blower door test and using an infrared camera.
