6 Reasons to Celebrate the Growth of the Ban Fracking Movement



This is a post from EcoWatch.com and needs to be shared. Check out this news about the Fracking controversy that is heating up.

These developments show that the movement to ban fracking grows stronger by the day. Fracking, and all the public health, environmental, economic and safety concerns that come with it, are not what our nation needs.
1. California Rising: The movement to ban fracking in California is growing at an incredible pace, and elected officials are starting to respond. Last Friday, following a packed hearing that reflected the diversity of Los Angeles, the City Council passed a motion to write a moratorium on fracking. This makes L.A. the largest city in the country to pass such a measure, and also follows the launch of California Farmers Against Fracking. Several other cities and counties are considering bans or moratoriums, and all of this helps build momentum to the big rally in Sacramento on March 15, where activists across the state will call on Governor Jerry Brown to ban fracking.
2. Colorado Fight Goes Statewide: In the last two years, Food & Water Watch has worked to support allies on the ground in Colorado to pass ballot measures to ban or place moratoriums on fracking, which is threatening major population centers across the state. Following recent victories in Fort Collins, Broomfield, Lafayette and Boulder, last Monday we joined local allies to launch Local Control Colorado, a statewide measure that would affirm the power of communities to ban or otherwise restrict fracking. We’ve also learned that a measure to protect communities from fracking in Broomfield, which had been challenged in the courts, was upheld.
3. Connecticut Moves on Fracking Waste: While it has not received the attention of fights in California, New York or Colorado, there is a move in Connecticut to ban the disposal of fracking waste in the state. We’ve been working closely with Citizens Campaign for the Environment, Grassroots Environmental Education, and others, and last Friday, the legislature held its first hearing on the measure, taking testimony in front of a packed house of residents opposed to fracking waste. This was the first step in the legislative process, and the first committee vote should be later in March.

Fracking is a technique for drilling oil that is bringing jobs and the promise of energy independence to our power hungry nation. The industry is said to be a major factor in the polluting of our water and food supplies. Check out this post and weigh in on the information. Go here for the full story:

Home Energy Solutions


Solar energy and wind power are the most often touted alternative sources of power for the home. In certain places you can add what is known as microhydro, a water powered system. Here's an article from Home Power magazine.

Making electricity from falling water can seem like magic, and that’s led to lots of misconceptions. Here, we’ll separate fact from fiction when it comes to what microhydro systems can and cannot do.
Residential-scale microhydro-electric systems have the reputation of being the holy grail of home renewable-energy (RE) systems. While they lack some of the hype, magic, and bling of solar-electric (photovoltaic) systems, microhydro systems are a simple technology that most people can understand…at least in general. In this article, we’ll look at some common microhydro system misconceptions, most of which come from folks looking for shortcuts to the reward of cheap electricity. 
Modern microhydro equipment comes from proven technology based on designs that have changed very little over the decades. Pelton and turgo wheels, the typical spinning water-wheel component, were invented in 1870 and 1919, respectively. The point is, this technology has proven its reliability and functionality with more than a century of performance.
The cost of these systems, and thus the cost of the resulting electricity, also has the reputation for being very reasonable when compared to other renewable or home-generated sources. While PV module prices have recently dropped, they are still a high-tech and expensive commodity. Microhydro systems can arguably be considered low-tech, with civil works and pipelines often being the majority of the system cost. Of course, the actual cost varies significantly from site to site, and from system to system.

Another element that keeps microhydro-generated electricity low in cost, and thus high in desirability, is the system’s continuous duty cycle. While PV systems only produce electricity when the sun is shining (and wind-electric systems when the wind is blowing), microhydro systems aren’t affected by nightfall or weather blocking the sun. Even a small hydro resource can provide electricity 24 hours a day, and often 365 days a year (if the water source is year-round). The bottom line for any renewable energy system is the amount of energy it can produce annually. A low power source working all of the time can often produce a lot more energy than a more powerful source that only works intermittently.
So, why doesn’t everyone have a microhydro system? Herein lies the challenge. A viable hydro resource is dependent on the availability of falling water at, or near, the site of the electrical loads. It is the weight or pressure of that flowing water that spins the turbine to produce electrical energy. Not everyone has access to a stream or spring of adequate volume on their property, nor does everyone have the topography to create the vertical drop needed to pressurize that water with gravity. See the “Microhydro Rules” sidebar for a formula about how water flow and vertical pressure (head) combine to determine the power available from a potential hydro site. That site-assessment formula will help debunk some of the myths that follow.

People who live near water sources can check to see if the area is good for adding a hydro-electric system to produce Alternative Energy for their homes. Home Power can come from many sources and this is one to think about if you have the resources nearby.
