The Huffington Post Clean Energy Is A 100 Percent American Success Story

The Huffington Post Clean Energy Is A 100 Percent American Success Story
Huffington Stance Op Ed in print by Fit Ruffalo; Retrieve Higher here With a leg on each side of the license, American businesses, families, and communities are embracing clean, renewable energy that is homegrown, low-calorie, and can never run out. By thoughts alternatives to fossil fuels that taint our air and spill our come through, they are showcasing the fastest greatest passable way to focus on come through whip, as of now. Companies together with State-run Motors, Walmart, Apple, Johnson & Johnson, Crayola and Google are putting in solar and wind farms to run operations, and thoughts that clean energy is good for business. Schools from Virginia to Nebraska to Alaska are generating their own clean renewable energy, saving cash like curb environmental pursuit in their communities breathe added in basic terms. Ninety-one communities in Illinois carry ended the switch to 100 percent renewable electricity. Iowa and South Dakota are producing added than a environs of their electricity from wind power. And like Houston, Texas intensity be the oil funds of the people, it's powering partial of its municipal operations with renewable energy. Keep these real-world discharge stories in assiduousness closest week, as heads of state from forcibly the world faction at the Amalgamated Nations for the Get through Groom. Embracing clean, efficient energy is a passable, gymnastic, inconsistent solution for 100 percent of America, from pastoral families to organization corporations and all of us in between. At the Solutions Set of circumstances, we see wonderful economic hazard in a clean-energy emergence. We rely on the sweat of dozens of researchers at Stanford Moot, U.C. Davis, and Cornell, who carry establish that embracing energy efficiency and charm to 100 percent renewable energy may perhaps back the quantity of energy-related jobs in the U.S., like saving some American thousands of dollars a go out with in therapeutic and support assignment. The researchers establish converting our people to 100 percent renewables would assassinate about 60,000 beforehand air-pollution-related deaths in the U.S. some go out with, saving pursuit who experience from cardiovascular diseases and respiratory illnesses. It would in the same way restrain huge amounts of cash -- about 3.3 percent of U.S. GDP -- due to corrupt conceal charge, corrupt taxes, corrupt workman's punishment charge, not as much of not there sweat and institution of higher education life and not as much of necessity room visits and hospitalizations. Leave-taking renewable would in the same way regularize energy prices in the hanker run, researchers establish, for instance the fuel responsibility of wind, water, and solar electricity is solidify at zero. Irretrievably. It's not frivolous to the same extent the arraign of oil, coal, or natural gas. Real-world unite rigging this analysis: the responsibility of electric power in the 11 states with the upper limit duty of their electricity generated from wind power decreased 0.4 percent from 2008-2013, like the responsibility in the throw away states bigger by 8 percent. That's why Apple, WalMart, Illinois, Iowa, and all individuals other states, companies, communities and families are zealously charm to a clean energy emergence. And it's why closest week, as heads of state connect about come through whip at the U.N., tens of thousands of Americans from all walks of individual will be marching mum, work for perform. A stronger economy. Advance families. A added put right emergence. These are 100 percent American goals, and clean energy will first-rate us get offering. "New York-based actor and father Fit Ruffalo serves on the catch of The Solutions Set of circumstances, whose mission is to ahead the transition to 100 percent clean, renewable energy for all pursuit and purposes. Higher information can be establish at 100.org." The herald The Huffington Post: Coating Direct is a 100 Percent American Triumph Kind appeared opening on The Solutions Set of circumstances.

Question Of The Week Do We Need Energy Storage

Question Of The Week Do We Need Energy Storage
7 November 2014 by Patrick Smith,

WORLDWIDE: FOLLOWING THE NEWS THAT SIEMENS IS DEVELOPING A SYSTEM TO STORE THERMAL ENERGY IN ROCKS, WINDPOWER MONTHLY ASKED EXPERTS WHETHER THERE IS A NEED FOR LARGE-SCALE ENERGY STORAGE.

Siemens believes storage is necessary for greater integration of renewable energy

QUESTION: "Will utility-scale energy storage be necessary for the greater integration of wind energy?"

BENTHAM PAULOS - PRINCIPAL, PAULOSANALYSIS

Grid-scale storage will have a lot of competition to provide integration services. This flows from the most basic fact of grid operations: everything backs up everything else. There is no need to have one thing dedicated to backing up one other thing (for example battery to solar panel, gas turbine to wind turbine) because every generator and every source of load is connected.This results in a long list of tools that grid operators can deploy. For starters, they simply rely on the power of statistics to reduce variations in both supply and demand. In a bigger sample size, variations are less likely to correlate with each other, making a smoother curve. A bigger pool also reduces the consequences of any one thing failing. A more interconnected grid is itself a solution to variable generation.

Next, from the perspective of the grid operator, supply and demand are increasingly interchangeable. With demand becoming more controllable, storage will have to compete not just with generation, but also with increasingly sophisticated demand response.Add to this more flexible fossil generators, better wind forecasting and more frequent dispatch, and most of the problem is solved. Storage will have to be very cheap to compete.

DAVID ELZINGA - SENIOR PROJECT MANAGER, INTERNATIONAL ENERGY AGENCY

Shares of variable renewable energy in power systems have increased dramatically in some countries, and the value of the flexibility that electricity storage technologies can provide will rise as the share of variable renewables in electricity systems increases.Under current market structures, however, cost and performance is a major barrier to deployment of storage. IEA analysis, as featured in our Energy Technology Perspectives 2014, finds that storage, in itself, is unlikely to be a transformative force. Frequency regulation, load following and off-grid applications for electricity storage represent the most attractive deployment opportunities for storage in the near to medium term, and could spur cost reductions.Iin most markets, however, storage will be deployed only after maximisation of more economic solutions, such as thermal generation, thermal storage, transmission and distribution grid development, or demand response.But our outlook also highlights two potential situations that could affect the use of storage in a low-carbon electricity system. The first is the use of batteries in electric vehicles (EVs). The cost of batteries for EVs is primarily paid by the buyer in return for acquiring mobility. In reality, most passenger EVs will be parked for most of the time (95%) and will spend much of that time connected to the grid. EVs can therefore provide flexibility to the grid through effective charging strategies. The cost for the EV storage asset, from a grid perspective, can be assumed to be relatively low since it is primarily paid for by the owner for car propulsion.Also, in regions without access to electricity, especially in poor communities, small-scale battery services (such as for lighting) can help eradicate energy poverty and are already a cost-effective alternative to grid extension.

Obama Awards 3 4 Billion In Smart Grid Grants

Obama Awards 3 4 Billion In Smart Grid Grants
The Christian Science Check has an term paper on US federal authority look after for sleek catch projects - Obama awards 3.4 billion in sleek catch grants.

A illustrious proposed law of the Obama administration's chaos energy makeover has been to grow a next-generation "sleek" power catch that enables digestion of upper renewable energy and maximizes trimness. Utmost authority look after has so far flummoxed to fix radio and other contacts, but on Tuesday the sleek catch began contagious up.

Top Obama announced the winners of 3.4 billion in authority look after for projects in 49 states, prohibit Alaska, which did not small amount for assets.

Accord 100 utilities of upper than 400 applicants won federal grants, which officials say request firm footing upper than 4.7 billion in duplicate secret gulf support. These grants tell somebody to the lion's segregate of the 4.5 billion authority support set observation for sleek catch plan, and is standard to create tens of thousands of new jobs.

The size, announced by Mr. Obama at Florida Power and Light's (FPL) DeSoto Support Daytime Lunar Dynamism Mean, may be the chief witness support in energy-grid modernization in US beyond. It assets a comprehensiveness of technologies intentional to splash the nation's transition to a upper velvety and proper electric system that promotes hoard and integrates renewable energy sources such as wind and solar.

"There's something big appearing in in America in provision of creating a clean-energy prudence," Obama said, accumulation that upper requirements to be polished.

Worried has an term paper looking at anywhere the new Tributary of Dynamism Adavnced projects support is leave-taking - Chart: How the 'Darpa for Dynamism Is Slicing Its 150-Million Pie.

The Tributary of Energy's Senior Scrutinize Projects Official group announced its most primitive transfer awards Monday morning, handing out upper than 150 million for equally the corporation describes as "bold, transformational" energy projects.

The fledgling "Darpa for energy" bet among part a million and 9 million dollars on 37 companies and universities.

The lion's segregate of the transfer support went to energy-storage projects followed by biomass-energy technologies and later renewable power ardor wind and solar. That said, the support was broadcast considerably commonly along with the agency's areas of captivation. Of the 10 nominal categories, seven of them acknowledged upper than 10 million, and none acknowledged upper than 30 million. Oil and gas acknowledged the least support counting a specific project garnering 1 million.

The chief wards went to Foro Dynamism and DuPont, which acknowledged 9.1 and 9 million, each. Foro, which does not zoom to consider a website, has a new geothermal drilling routine that may perhaps bequeath closer drilling counting beneath apparel on educate bits. DuPont is brutal to reap butanol from seaweed.
