It has taken the last 30 years to get to the point where we can have this conversation. Is it in time? I do not know, but it sure feels good.

Solar Power vs. Wind Power Pros and Cons

Solar Power vs. Wind Power Pros and Cons

By Go Green In Your Home in How to Save Electricity

After doing some research on renewable energy systems or alternative energy systems as many will call them, I wanted to get the information out there as far as the advantages and disadvantages of the 2 main renewable energy systems, wind turbine generators and photovoltaic solar panels.

Both solar panel and wind generator systems are similar as far as how they are setup. You can have the wind generator grid tied or off grid, same as solar panels. Both the solar panel (photovoltaic panel) and wind generator will need a battery bank if you are using an off grid system. Both of these renewable energy systems will produce clean energy and help the environment as well as save you money in your home!

Advantages and Disadvantages of Wind Generator Systems and Solar Panel Systems

Now onto some of the advantages and disadvantages of each alternative energy system. None of this information is from my own personal experience as I do not have the financial funds to support the research. So the information about these renewable energy systems have came from researching the internet, talking to people that have these alternative energy systems, and of course some calculations of my own (prices, efficiency, etc.).

Wind Turbine Generator System Pros and Cons

The main advantage of wind generator is that they can produce electricity day or night as long as there is wind. Wind generators need less space on your land to produce sufficient electricity. Wind generators are able to produce more electric for the same price. If you spend $1,000.00 on wind generator you can produce 1kW – 2kW, with solar panels you may only produce around .5kW – .75kW with the same $1,000.00. Wind generators have moving parts, so there is always wear and tear on these moving parts. Bearings can go bad, propeller blades can be struck by objects, and heat may be generated. Your wind generator will be installed on a tower or pole of some sort to gain height where there is more wind, allowing lighting to possibly strike your wind generator. As wind hits the propeller blades there will be noise created, think of a fan and how they sound, or even taking a rope and swinging it fast in circles. You will get some of this noise from your wind generator. The propellers of the wind generator can also produce shadows flickering. Birds can get killed from flying into your wind generator’s propellers. There are vertical wind generators which will prevent this. So the quick break down of the wind generator system:

250 Coal Fired Power Plants Close By 2018 – This is very good news

Posted on by
Reply

Let me be clear here, the transition to clean energy sources will be painful because it is unplanned. Consider this: What if the Federal Government had a plan to move away from fossil fuels with clear benchmarks for the shift and training programs to move workers into that market. Well, plants would be closed on a schedule that everyone knows in advance, and there would be no pain. Only growth and prosperity. The way we are going about it now, Nuclear Power gets classified as “green”, plants are shuttered and workers are thrown out of their jobs. Brilliant.

Two Ohio coal-fired plants to close, deepening industry decline

By Emily Flitter | NEW YORK

Electricity company Dayton Power & Light said on Monday it would shut down two coal-fired power plants in southern Ohio next year for economic reasons, a setback for the ailing coal industry but a victory for environmental activists.

Republican President Donald Trump promised in his election campaign to restore U.S. coal jobs that he said had been destroyed by environmental regulations put into effect by his Democratic predecessor, Barack Obama.

Dayton Power & Light, a subsidiary of The AES Corporation, said in an emailed statement that it planned to close the J.M. Stuart and Killen plants by June 2018 because they would not be “economically viable beyond mid-2018.”

Coal demand has flagged in recent years due to competition from cheap and plentiful natural gas.

Solar Power Had A Kick Ass Year – Let the sun shine

The news only gets better for renewables. Wind did not keep pace with Solar but wind had a huge head start. Coal is fading in the rear view mirror and natural gas is neck and neck. I think the US is finally catching on, but you can bet the first things Trump will go after will be subsidies and the EPA.

More solar energy was added in 2016 than natural gas or wind

Jan 1, 2017

Renewable-energy growth has accelerated in 2016, but this may go down as a milestone year for one renewable-energy source in particular.

Together, all renewable-energy sources are expected to account for 8 percent of U.S. electricity-generation capacity in 2017, according to the Department of Energy, and solar energy is responsible for most of that growth.

For the first time ever, new solar-generating capacity is expected to exceed new generating capacity for wind and natural gas.

DON’T MISS: We’re there! Renewables now cheapest unsubsidized electricity in U.S.

The final tally won’t be available until March, but enough new solar installations were expected to be completed in 2016 to outpace wind and natural gas, according to Scientific American.

A total of 9.5 gigawatts of solar-generating capacity were expected to be built in 2016, tripling the amount installed in 2015, the magazine said, citing Energy Department data.

That amount would exceed the anticipated 8.0 GW of natural gas capacity, and 6.8 GW of wind capacity.

Coal Can’t Be Resurrected – Not even the President is that powerful

Posted on by

Natural gas is cheap. Solar Photovoltaics are even cheaper. The job prospects in renewables are growing as fast as miners jobs are falling. Donald Trump may think he is all powerful but even if the Russian mob boss Putin joins in, China, India and Australia never will. Seems to me that is the end of the story.

Report: 1 in 50 new U.S. jobs came from solar last year

Employment in the industry rose in 44 states and is expected to continue growing

Senior Reporter, Computerworld | Feb 7, 2017 1:51 PM PT

One out of every 50 new U.S. jobs last year came from the solar industry, with growth in that industry outpacing the overall U.S. economy by 17 times, according to a new report.

Overall, there were 260,077 solar workers in 2016, representing 2% of all new jobs, according to The Solar Foundation’s Solar Jobs Census 2016.

Solar employment increased by more than 51,000 workers, a 25% increase over 2015, according to the report. Solar industry employment has nearly tripled since the first National Solar Jobs Census was released in 2010 — rising at least 20% annually for the past four years.

Along with growth in solar and other forms of renewables, energy storage is a rapidly growing industry, comprising 90,831 jobs — of which 47,634 are focused on battery storage.

A Comprehensive Approach To Energy Efficiency – Doing less with more

Posted on by

To Not talk about how disastrous Trump’s Presidency will be for the environment and the energy industry I decided to return to my roots in the residential market. Todays article is a bit old but its message is timeless. We have been concentrating on single devices like furnaces, refrigerators, windows seen as a whole instead of a holistic approach to a house.

https://www.greentechmedia.com/articles/read/the-real-problem-with-energy-efficiency

We’re Doing Residential Energy Efficiency All Wrong

Utilities are now spending nearly $7 billion a year on energy-efficiency programs. It seems we have little to show for it aside from expensive consultants who will model any results you would like.

These programs tend to focus their marketing on the energy savings or money savings from the projects. Consumers don’t care. If they did, we would see geometric growth instead of a resounding “meh.”

Others focus on better financing products, slicker sales pitches, faster energy audits, higher rebates or any of a myriad of other things.

In the residential sector, none of these are the problem. The lack of sales is the problem.

Projects are not being sold and implemented in substantial numbers. We need to slow it down, build relationships with consumers and educate them, learn and think systemically about the problems they have, and arrive at solutions that fit homeowner budgets.

Why the rise of green energy makes utility companies nervous.

By

     Mark and Sara Borkowski live with their two young daughters in a century-old, fifteen-hundred-square-foot house in Rutland, Vermont. Mark drives a school bus, and Sara works as a special-ed teacher; the cost of heating and cooling their house through the year consumes a large fraction of their combined income. Last summer, however, persuaded by Green Mountain Power, the main electric utility in Vermont, the Borkowskis decided to give their home an energy makeover. In the course of several days, coördinated teams of contractors stuffed the house with new insulation, put in a heat pump for the hot water, and installed two air-source heat pumps to warm the home. They also switched all the light bulbs to L.E.D.s and put a small solar array on the slate roof of the garage.

The Borkowskis paid for the improvements, but the utility financed the charges through their electric bill, which fell the very first month. Before the makeover, from October of 2013 to January of 2014, the Borkowskis used thirty-four hundred and eleven kilowatt-hours of electricity and three hundred and twenty-five gallons of fuel oil. From October of 2014 to January of 2015, they used twenty-eight hundred and fifty-six kilowatt-hours of electricity and no oil at all. President Obama has announced that by 2025 he wants the United States to reduce its total carbon footprint by up to twenty-eight per cent of 2005 levels. The Borkowskis reduced the footprint of their house by eighty-eight per cent in a matter of days, and at no net cost.

Solar That Comes With Batteries – What a thought

Posted on by

Let me say, right off the bat, there are other better storage mechanisms then batteries. But if this becomes a market trend, well then whatever.

http://energy.sandia.gov/installation-of-new-englands-largest-battery-energy-storage-system-is-underway/

Installation of New England’s Largest Battery Energy Storage System is Underway

NEC Energy Solutions has begun the installation and commissioning of a 2 MW, 3.9MWh GSS® grid energy storage solution for the Sterling Municipal Light Department (SMLD) in Sterling, Massachusetts. Once complete in December 2016, it will be the largest system of its kind installed in New England and the first utility scale project in the State. In the event of an extended grid outage due to a natural disaster, this utility scale Battery Energy Storage System (BESS) can be used to power local emergency response facilities using power generated from two nearby solar plants. The system will also provide enhanced clean energy usage and cost savings to the town of Sterling.

Sandia provided SMLD with analysis to identify the optimal deployment site, amount, and installation type of energy storage within budgetary limits. Sandia also assisted with crafting a Request for Proposals (RFP) for the BESS system, vetting bids, and installing and dispatching the system. “Sandia was instrumental in helping us pull that together. We had developed a minor RFP and they brought in the technical support that we needed to get this done right. Working with Dan Borneo and Ray Byrne on this project has been very valuable to us,” said Sean Hamilton, General Manager of SMLD.

Going forward, Sandia will help SMLD oversee the operation of the BESS to optimally maximize economic returns while safeguarding SMLD’s ability to provide resilient power; monitor BESS operations; and collect operational data for one-year post-commissioning. The data will be used to further the U.S. Department of Energy’s/Sandia’s understanding of the benefits and applications of battery storage in the utility context and provide a number of important battery use cases in resiliency, cost savings, and revenues that can be adopted by numerous municipal utilities and vertically integrated utilities.

Republicans Favor Solar Power – Something their Leaders should bare in mind

Posted on by

I heard this on NPR and I just had to put it up here. I especially like that people like Bruce Rauner and Donald Trump are so out of touch with their base. But what does it say about the Democrats.

https://www.greentechmedia.com/articles/read/california-republicans-are-5-times-more-likely-to-buy-solar-than-democrats

California Republicans Are 5 Times More Likely to Own Solar Than Democrats

Republican voters and elected officials are generally considered hostile toward renewable energy. That’s likely because many prominent Republicans deny humanity’s contribution to climate change and oppose subsidies for clean energy technologies, despite the fact that fossil fuel industries benefit from billions of dollars in tax breaks.

Instances like the snowball toss made by Republican Senator James Inhofe, chairman of the Environment and Public Works Committee, coupled with his record of voting against clean energy legislation, help to cement the perception that conservatives widely oppose the adoption of low-carbon technologies like solar and wind.

This year’s GOP platform states, “We encourage the cost-effective development of renewable energy sources — wind, solar, biomass, biofuel, geothermal and tidal energy — by private capital.” However, Republican presidential nominee Donald Trump has repeatedly bashed the clean energy sector, called climate change a hoax created by the Chinese, and recently called the solar industry “a disaster.”

Major Environmental Effort – 2018 HFC Accord is a beginning

Posted on by
Reply

Most Americans don’t realize that controlling HFCs in the world is a big deal. That is because North America basically banned them a long time ago. For that matter most of the developed world has stopped using them but huge chunks of the planet still do, like China and India. So this accord is a very big deal.

Climate change: global deal reached to limit use of hydrofluorocarbons

Global deal on HFC greenhouse gases set to bring about ‘largest temperature reduction ever achieved by single agreement’

, , and agencies

A global deal to limit the use of hydrofluorocarbons (HFCs) in the battle to combat climate change is a “monumental step forward”, John Kerry, the US secretary of state, has said.

The agreement, announced on Saturday morning after all-night negotiations in Kigali, Rwanda, caps and reduces the use of HFCs – a key contributor to greenhouse gases – in a gradual process beginning in 2019, with action by developed countries including the US, the world’s second worst polluter.

More than 100 developing countries, including China, the world’s top carbon dioxide emitter, will start taking action in 2024, sparking concern from some groups that the action would be implemented too slowly to make a difference. A small group of countries, including India, Pakistan and some Gulf states, also pushed for and secured a later start in 2028, saying their economies need more time to grow. That is three years earlier than India, the world’s third worst polluter, had first proposed.

Worldwide use of HFCs has soared in the past decade as rapidly growing countries like China and India have widely adopted air conditioning in homes, offices and cars. But HFC gases are thousands of times more destructive to the climate than carbon dioxide, and scientists say their growing use threatens to undermine the Paris accord by 195 countries, an agreement last year to reduce climate emissions.
