Most of The World Could Be 100% Powered With Renewables by 2050

SolarEdge is on the cutting edge of solar technology for the 21st century. This inverter allows one to install panels on a garage roof, and convert the electricity efficiently into 220V for quick-charging an electric car or two. The system can be netmetered or it can be independent of grid power. If independent, like an off-grid home, once the car batteries are charged, excess solar power is not captured.

The new SolarEdge HD-Wave technology inverter is a much smaller and lighter form factor, allowing for one-person installation, and easier/less costly shipping. This was the winner of the 2016 Intersolar award, breaking the mold of traditional inverters. Using advanced digital processing allows the inverters to create a clean high definition wave. This also means less magnetic and heavy cooling elements are needed inside. Additionally, these inverters are highly efficient - in a class of their own- providing more energy production for an improved ROI on your solar power system.

I'm pretty excited about these systems, and I've gotten a quote. At this point, I'm just trying to figure out whether to grid-tie or not. Federal 30% tax credit applies in 2019.

Lewis and Curry are underrepresenting the risks of climate change.

Nic Lewis | Risk and Well-Being

And this is why I think scientists like Judith Curry and Nic Lewis don’t really get risk. They argue that doubling atmospheric CO2 isn’t much to worry about because we may only warm a little. Yes, we may warm only a little; but then again we may not. Here is the climate sensitivity table from a recent paper by the two (click for larger image):
...
The pre-industrial revolution level of atmospheric CO2 was 280 parts per million (ppm). We are now at 400 ppm, so to double from pre-industrial concentrations, we would need to get to 560ppm. Co2 concentrations are also rising at around 2.25-2.50 ppm per annum. So if climate sensitivity to a doubling of CO2 were 3 degrees Celsius, we would get 2 degrees of global warming if CO2 concentrations reached around 450 ppm, which will be in about 20-30 years time. Two degrees of warming is considered (somewhat arbitrarily) to be the borderline for dangerous climate change.
...
It gets worse. What if their climate sensitivity numbers are wrong. Curry and Lewis use one particular approach to reach their figures, but there are others.

2019 is the last year to take the full 30% tax credit on residential renewable installations. If my Utility will allow me to Netmeter, I'm going to install a 7.6kW solar charging system on my garage. It will recharge 2 electric cars. I will have zero in petroleum bills after that. I also get a state tax credit - total tax credit will pay for almost 40% of the $14K cost.

This is on top of a $7500 federal tax credit I got this year on my Chevy Volt.

More people should really look into this - it's free money in the bank!

Yes those initiatives are really good and necessary, sadly US have a president that instead want to spend billions of dollars propping up unprofitable coal plants.

While even his own federal agencies warns about the devasting effects of manmade global warming.

"The impacts of climate change are already being felt in communities across the country. More frequent and intense extreme weather and climate-related events, as well as changes in average climate conditions, are expected to continue to damage infrastructure, ecosystems, and social systems that provide essential benefits to communities. Future climate change is expected to further disrupt many areas of life, exacerbating existing challenges to prosperity posed by aging and deteriorating infrastructure, stressed ecosystems, and economic inequality. Impacts within and across regions will not be distributed equally. People who are already vulnerable, including lower-income and other marginalized communities, have lower capacity to prepare for and cope with extreme weather and climate-related events and are expected to experience greater impacts. Prioritizing adaptation actions for the most vulnerable populations would contribute to a more equitable future within and across communities. Global action to significantly cut greenhouse gas emissions can substantially reduce climate-related risks and increase opportunities for these populations in the longer term."

Despite all the efforts to lower CO2 emissions, worldwide CO2 emissions are still on the rise. Think about that. Wind energy has made huge inroads throughout the world. In your state of Texas, in 2017, wind accounted for 15% of electricity generated. It's probably almost 20% now. And still, worldwide - CO2 emissions are up. You can point to other nations, like so many deniers like to do, but we're all in this together.

That why it's so good that more and more people are making their voices heard and demanding action on climate change. For example that you have school strikes and climate events in nearly one hundred countries and over one hundred American cities and towns on friday.

"Every year of their lives has been one of the warmest recorded. Extreme weather events, including floods, wildfires and heat waves, are becoming the new norm. Many believe that, if nothing is done to stop global warming, their generation will be left to deal with catastrophic consequences.

That's why, on March 15, tens of thousands of students worldwide will be cutting class and taking to the streets to demand that elected officials act."

This can be a positive sign of change.

"Perry told reporters at the CERAWeek by IHS Markit energy industry conference in Houston that he’d be open to meeting with Ocasio-Cortez to discuss ways to reduce emissions.

“I don't think the representative should be castigated or pushed aside just on the face of her comments relative that she wants to live in place with clean air and water,” Perry said. “So do I.”

He later suggested a blanket rejection of the Green New Deal would be counterproductive to the goal of addressing climate change, which he shares."

[h=2]“Market Bloodbath”: Too many new remote renewables projects means high losses[/h]
As Australia push-pumps “renewables” into remote locations some of their incomes are suddenly being cut because the losses (as they transmit across long lines) are higher than they expected. On March 8th the AEMO rerated many generators and this year it’s being called a bloodbath for wind and solar. Some of them, like AGL’s Silverton wind farm face losses of 20%.
It all revolves around something called Marginal Loss Factors, a value that is set by the AEMO each year for each generator. The rating is reduced by transmission losses over distance and also by “congestion” from other renewables which are popping up in the same remote locations far from the cities and industries that need the electricity they make. This sudden loss of expected income threatens new wind and solar projects (as it should — hello market signal!) Sometimes the loss factors are hard to predict years in advance which makes it difficult to also predict whether a project will return a profit (even despite the guaranteed subsidies).
[h=3]Another renewable inefficiency strikes — “marginal loss factors”[/h]Generators are paid according to the electricity that arrives rather than what they produce at the plant. (Seems fair). This is called the Marginal Loss Factor (MLF). Ideally they’d get paid for an MLF of 1.0 or higher (which means paid for every MWh or potentially even more if they are based in an area where there is a lot of demand and not many generators). Loss factors range from 0.8 up to 1.2, though most of them are close to 1.000. But this year there are losses across the board and only a few gains. An MLF below 1.0 is bad news for generators. In the extreme case of Silverton, the marginal loss factor fell from 1.0 to 0.79 which means they only get paid for 79% of what they produce. One fifth of the energy generated is not getting to where it is needed and won’t get paid for. Karadoc Solar Farm dropped from 0.94 to 0.78. These are some of the biggest falls.
It’s affected base load providers too, to a lesser extent. Snowy Hydro, and some gas plants are down about 5%. If dumping too much capacity on the grid causes the MLF’s to sink, surely that is another “renewable cost”? Add it their bills…
The big inescapable problem for unreliable generators is that they need acres of land which makes it expensive to build them near the demand. . . .

But they cannot be AC lines for the types of distances and intermittency. They need to be DC lines. HVDC. Second paragraph:

HVDC allows power transmission between unsynchronized AC transmission systems. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows transfer of power between grid systems running at different frequencies, such as 50 Hz and 60 Hz. This improves the stability and economy of each grid, by allowing exchange of power between incompatible networks.​

Texas continues it's wind energy revolution!

Texas wind generation keeps growing, state remains at No. 1 - HoustonChronicle.com

The state’s wind energy production, meanwhile, is only expected to increase and provide a growing share of the state’s electricity as advancing technology allows turbines to generate at lower wind speeds and improved weather forecasting makes it easier to integrate it into the grid.
...
Texas had more than 22,000 megawatts of wind power, ...
...
A megawatt can power roughly 200 homes during periods of peak demand.

Even a non-scientist like Jack should be able to do that Math - that's 4,400,000 homes at peak demand!!!

Of course there is more than just the rating plate math, because the wind turbines do not produce that output all the time.

Wind energy, may have a role in our energy future, but only if it can compete with solar.
In some locations wind and solar supplement each other well, others not so much.

Not a problem in Texas. They have found that they can offer some of the most affordable electricity in the United States, by using a Wind-First philosophy. The wind is FREE energy, and they take full advantage of that. Not only does their electricity have some of the most affordable rates in the nation, but they are poised to improve on that dramatically, in the not-to-distant future, as the cost of fossil fuels start rising again, after the temporary hiatus on rising fossil fuel prices.
