"I want to install a simple solar PV system in the rooftop of my house. How do I go about it??"

This is the procedure for a simple system with Net-metering and no Batteries.
Step 1: calculate rooftop area in Sqft or Sqm Say 100 sqm++

of shadow free area. You need to own the rooftop.
Thumb rule: 1kW needs 10 Sqm/100Sqft
In our case, we can build 10 kW. You need own the rooftop.
Step 2: Check Ebill: say the consumption is 1500 units (kWh)/month. In India, peak sunshine hours = 5.5 hours. In order to++

zero your ebill, you need 1500/(30 x 5.5) = 9 kW system.
Step 3: Check sanction load in ebill. You solar size cannot exceed this value.Say sanction load = 10 kW
Step 4: Choose the min of the values in 1, 2 and 3 and that is the size of the system. In this case,it is 9 kW++

Nature is angry - and we foool ourselves if we think we can fool nature. Our Earth is issuing a cry: "STOP". The climate crisis is caused by us, and the solutions must come from us -@UN Chief @antonioguterres at #ClimateActionSummit on the need to cut greenhouse gas emissions
@UN @antonioguterres "We are at the beginning of a mass extinction, and all you can do is talk about eternal economic growth" - @GretaThunberg makes a passionate plea for #ClimateAction at today's #ClimateActionSummit in New York. Watch live 🎥webtv.un.org/live/ #UNGA
@UN @antonioguterres @GretaThunberg @GlobalGoalsUN Indian PM @narendramodi - "We are going to increase the share of non-fossil fuels to 174 gigawatts in 2020, and to futher increase #renewableenergy to 450 gigawatts"

India has installed #solar panels on the roof of the @UNHQ building in NYC

Why are we here? Only 100 companies are responsible for 71% of global carbon emissions since 1988. #PeopleVsOil (1/7)
Many of the refineries here are operated by some of those very companies, like ExxonMobil, BP, Chevron, and Shell. #PeoplevsOil (2/7) bit.ly/2ue11eC

Still think #BigOil is the answer? Consider this:

Before 1886, people travelled via horse and buggy.

In 1858, the refining of #CrudeOil crude oil allowed for larger-scale processing & helped spur the #gas gas engine automobile (this is the first - 1886).

The Model T, produced by @Ford, was the first mass produced vehicle, but not the first auto.

Innovation led to bigger, enclosed cars.

Recent @bradplumer article for @nytimes asks - will utilities replace #coal with #naturalgas or #renewableenergy? Utilities are diverging along those paths, but the math for renewable and storage economics is more compelling than many understand. A thread:
1/ If you concede that natgas or some "firm" capacity is for balancing and to meet peak, it's fair as a rule of thumb to say solar plus storage replaces that service until we get to much higher penetrations of renewables. We can rely for now on 450 GW of existing gas.
2/ @Lazard LCOE v12 puts the LCOE of natgas at $41-74. Consider two interesting numbers. The first is yesterday's contracts for 1200MW solar and 590MW storage in Nevada. Only one contract for 200/100 MW of solar + 4hr battery announced prices. greentechmedia.com/articles/read/…

So China's MacMines shelves its decade long development of its Galilee Coal project, China Stone. A $6.7bn high ash, low energy (HALE) thermal #coal export proposal. abc.net.au/news/2019-05-2… by @LGartry
Why? 🇨🇳 is moving to decarbonise & transition its economy as fast as it can. China is the world's biggest producer, consumer & importer of coal. But China's coal consumption peaked in 2014. 🇨🇳 will probably cease thermal coal imports medium term, relying on their domestic mines.
China just announced a 21GW subsidy free wind & #solar tender, for construction completion by next year. Grid parity for renewables in China by 2020. That is well ahead of target. Zero pollution, zero emissions domestic production. bloomberg.com/news/articles/… by Feifei Shen @business

#oilandgas flimflam men are lying! Journalists should not repeat the lies!

They want the public to believe that natural gas is a solution for #climatechange.

IT IS THE PROBLEM.

U.S. GHG emissions are rising not decreasing as flimflammers claim. 1/4

Natural gas is #methane or CH4 and it's a super pollutant that is over 86 X more potent at warming the planet than CO2. But, it doesn't stay in the atmosphere for very long and that's where the HOPE for STOPPING #climatechange is. 2/4
Because #methane is short-lived, if we STOP #fracking and #KeepItInTheGround our planet will have an immediate response and the rapid warming will slow giving us time to solve CO2 which stays in the atmosphere for a very long time. 3/4

In Congress, we’ve had a good record of passing bipartisan budgets in recent years. @realdonaldtrump and his impulsive White House haven’t helped.
Now he’s thinking of making cuts to #healthcare, education, protection for our air and water, #renewableenergy programs, and critical infrastructure funding to rebuild our roads and bridges – all to fund his big, dumb wall.

Mr. President, how about you let our bipartisan, bicameral #budget process play out and just stay out of it. #TrumpBudget

I can’t wait for y’all to get to know @BetoORourke. Those of us here at Veterans for Beto were grassroots organizers for his Senate campaign last summer and fall. Those of us in our group know Beto as well as anyone, and our support for Beto has not wavered since the mid-term.
We’re #Texas #veterans, y’all. All of us wore the uniform (or were close to someone who did), we’re patriots, and we love Texas and our country. We’re also mostly pretty cynical about politics and politicians, which is why it’s remarkable how much we support @BetoORourke.
This veteran had never gotten off the couch to support any politician. But there I am, putting up road signs in September Texas heat. I personally knocked probably over 1,500 doors, and Vets for Beto thousands more. For @BetoORourke, I, and my colleagues, showed the fuck up.

I thought it worth a thread suggesting something material might just have changed in Australia's #1 thermal #coal export destination - Japan 🇯🇵. We at IEEFA have written about this quite a bit, but mainly about the growing momentum to exit #coal. ieefa.org/ieefa-japan-ea…
On the other side, @JoshSHill wrote about TEPCO, Japan's biggest thermal power generation firm. They just announced a joint venture MoU with @Orsted for offshore #wind.
Anyone else seeing a Japanese corporate pivot towards #RenewableEnergy internationally?
reneweconomy.com.au/japan-looks-to…
TEPCO also this week announced it will co-seed CleanGrid Partners' US$60m #solar infrastructure fund for South East Asia, starting with distributed, off grid solar replacing imported diesel applications in Philippines. A smallish step, but a good one. ✔️ straitstimes.com/business/compa…

Hi guys! @AtteHarjanne and me just published a paper "Abandoning the concept of #renewable #energy" at Energy Policy. In it, we argue that the concept of #renewableenergy (RE) is outdated. 1/

First, a link to the paper that should work until Feb 14:

sciencedirect.com/science/articl…
What we argue here is that using what is basically a 1970s-era definition of renewable energy, and conflating "renewable" with "sustainable" or even "clean," is becoming more a hindrance than a help in meeting the main challenge of the early 2000s - #climatechange . 2/
We argue that the concept of RE was largely set in stone well before the magnitude of #climate challenge, and actual problems with some sources that are technically renewable, was understood. This has resulted to, e.g., using the "renewable" label to cover all bioenergy. 3/

Key finding in Minnesota decarbonization study: the local strategy––maximizing distributed energy resources––saves customers (nearly) the most money. Higher rates but lower use. mcknight.org/programs/midwe… #distributedenergy #renewableenergy #local
Bonus: the inexpensive Local Decarbonization scenario also includes 13 gigawatts of rooftop solar PV in Minnesota!
Another bonus: decarbonization insulates Minn. from high gas costs. In a high-cost scenario, shifting to renewable energy saves over $40 billion by 2050!

Today @SynapseEnergy released a new report commissed by @NRDC on the opportunities and challenges for decarbonizing heating in #California buildings. Here is a quick summary thread.
CA's buildings are responsible for 25% of the state's #GHG #emissions and more than half of those already come from combusion furnaces and water heaters.
Switching to efficient electric heat & hot water will have a significant impact on reducing gas use in California buildings. As CA’s electric grid shifts toward clean, #renewable energy sources, #emissions from electric heat will continue to drop.

There's a gentleman who always speaks about #venturefunding in the #renewableenergy sector. Honestly, my eyes glaze over when he goes on about turbines and solar panels and the projects he's working on in Brazil. This is because venture funding is not my area of strength.
One day he told me his revenue projections and my eyes popped at the numbers.

Let's start here: Dan Rather does a good job summarizing the Sinclair propaganda facet of Trump's authoritarian regime.
Rump's authoritarian behavior includes subverting democracy, failure to be transparent, failure to be accountable, nepotism, cronyism, and many dimensions of financial corruption.
Trump's authoritarianism includes thwarting the will of congress, obstructing the protection of the environment, and putting property & people & planet at unprecedented risk.

Six #nuclear reactors closed since 2013. By my count, up to 23 more reactors may retire w/o policy or market conditions improving: 21.6 GW = ~1/5th of US fleet, 4% of US #electricity--and crucially, 12% of emissions-free generation.

So what's killing nuclear power in the U.S.?
In a new @MIT CEEPR paper -- 1 part #energy #economics & 1 part film noir murder mystery! -- I provide the 1st empirical estimates of what's driving down #electricity market prices & killing profitability of 19 #nuclear power plants across @pjminterconnect ceepr.mit.edu/publications/w…
