Off Grid Solar Living: Lessons in Energy Efficiency This story is meant to provide information about off grid living, meant to teach you or inspire you. I get a lot of people that ask me ‘What’s it like to live off the grid?’ I think a lot of people picture us huddled around a candle in darkened cabin in the middle of the woods.
5 breakthroughs that will make solar power cheaper than coal There was some good news last week. While Washington was busy holding the global markets hostage and placing billions in badly needed R&D funding on the chopping block, a new report from REN21 (the Renewable Energy Network for the 21st Century) showed that global investments in renewable energy jumped 32 percent to a record $211 billion, this despite a downturn in the economy and massive R&D cuts in clean energy. It's a little reassuring that progress marches forward, despite our nation's best efforts to stop it. Solar in particular appears to be growing in leaps and bounds due in large part to a 60 percent drop in price per kW (kilowatt) production in just the past three years. In many regions solar power is getting competitive with coal power, and its price will continue to drop with the onset of a many new advancements in solar technology. 1.

almost free garage heat – just drink a lot of soda I’ve had a few days during the HMX build while I’m either waiting for parts or waiting for something to dry and had some free time. I’m not exactly one to sit and watch TV when I have nothing planned, so I set out on another project. While I have electricity out to the garage now, heat has been an issue all winter long. Mattar graciously lent me his kerosene heater, which did an okay job of taking the bite off the chill. Insulating the garage would go a long way to help keep the bitter Vermont cold out, but that’s a project for another day.
New Catalyst Lets Us Store the Power of the Sun In Brief Scientists have found a way to “crack” water three times more efficiently using solar- and wind-generated electricity, which means it’s possible to store renewable energy for later use. Rainy Day Energy One of the problems with using renewable energy sources is that you’re overly dependent on the fickle whims of weather.

Solar Greenhouse Building Our BatchGeo world MAP shows the locations of green building and renewable energy projects featured on Solaripedia. ALMOST ANY STRUCTURE that is built to look like a solar greenhouse will work. That is to say, the solar greenhouse concept is so right that you can ignore (or not know) the fine points of solar design and still build a house with much less need for supplemental heat than a traditional greenhouse. But once you understand a few basic solar-greenhouse design ideas, you can easily put together a greenhouse that truly lives up to the label solar, and provides remarkable efficiency. ©1978 Organic Farming and Gardening Dave MacKinnon, Ph.D., ORGANIC GARDENING greenhouse designer, has put it all together after three years of experimenting and has created a design formula that gardeners in any climate can follow.
Bob Lang’s Better SketchUp Guide “When I became adept at modeling in SketchUp, I became a better woodworker, as have most people I know who have learned how to use this program.” – Bob Lang This quote is from the opening pages of Robert W. Lang’s new book titled New Woodworker’s Guide to SketchUp. Comparing Solar Air Heater Designs & Performance — Stonehaven Life In my last post – Solar Heat: Free for the Taking, I covered some of the background information on how to take advantage of the sun’s energy to help heat your home. Building a solar air heater is an easy and rewarding project for both beginner or experienced DIYers and there are all kinds of different designs and plans floating around – just ask Mr.Google. The most popular and flexible DIY solar heater projects seems to be the self-contained unit which can be attached to a wall or roof for supplementary heat. Today I’m going to look at 4 of the most popular variations of these units. And thanks to Gary & Scott, a couple of dedicated solar enthusiasts, I can share a brief summary of the comparable performance you might expect from these units. Design basics
South African team may have solved solar puzzle even Google couldn't crack It is a problem that has so far stumped even Google’s brainy engineers – how to generate cheap solar electricity using a small-scale array of mirrors to concentrate the sun’s energy. Now a team at a South African university – led by a former Intel strategic planner – believes they have cracked it. Once they have completed a prototype system in October they have big plans for rolling out the technology.
One of the World's Largest Solar Farms to Be Built in California Desert Solar is going big. Again. The federal government on Monday green-lit a 485-megawatt solar plant that will generate enough carbon-free electricity to power 180,000 homes when it comes online in the Southern California desert. During the Great Recession, there was nothing unusual about billions of dollars in federal stimulus money fueling big green dreams of carpeting the Mojave Desert with giant solar power plants on government-owned land, a cornerstone of the Obama administration’s efforts to fight climate change.
