About 1 in 3 Australian homes have rooftop solar.

Here in America, it's less than 1 in 10.

And Denver is sunnier than Melbourne.

The difference is the bill.

A 7 kilowatt system here runs a median of $28,000.

That's $18,000 to $24,000 more than the exact same system costs in Australia.

Up to 7 times the price.

Australia is a rich western country like the US and it went solar for one reason above all others.

Money.

The revolution in the lucky country is a product of cost, which has been going down, under.

I know exactly how we got here, because I've lived it.

When I put solar on my own house, the panel sat there for months waiting on paperwork.

Australia treats a solar install like buying a refrigerator.

We treat it like a zoning hearing.

And their head start is compounding.

Australians are adding home batteries at a rate of 2000 a day, and the flood of storage helped to drop the cost of generating power by 12% in a single quarter.

electricity for everyone, including the people with nothing on the roof.

So what does Australia know that we don't?

What's the gap costing you and what would it actually take to catch up?

I'm Matt Farrell, welcome to Undecided.

This video is brought to you by Incogni.

Here's the part that stings.

America literally invented photovoltaic technology that we know today.

Germany provided the market for it and China industrialized it.

So how is it that the lucky country is eating our lunch after slathering it in electron Vegemite.

There's a big obvious reason why solar is taking off faster in Australia than the US.

It's the first of several.

Right now, American energy policy is actively anti-renewables.

The Trump administration's energy policy is slowing down solar.

This year, he got rid of tax credits that existed for solar at the end of 2025.

Although far from perfect, they made residential solar 30% cheaper.

And that's not all.

Trump spent $2.6 billion taxpayer dollars to stop wind projects and development, funneling that money into fossil fuel extraction instead.

And he's fired renewable energy lab researchers, canceled renewable money from farmers and ranchers, and slashed billions in energy grants to states that didn't vote for him.

This is setting America back.

Canary Media expects peak annual solar installs to be held back for an entire decade.

These policies make solar more expensive and they convince people to be less enthusiastic about renewables.

But while this explains what sets America behind Australia right now, it doesn't explain how we got here.

We can't just pin all of this on Trump.

America started falling behind two administrations ago, back when Washington was actually trying to help.

To see how we really got here, we have to go back decades and we have to go to Australia.

And later I'm putting my own solar invoice on the table.

43 panels, one number at the bottom, and a gap so big it still bugs me.

But first, a word about paperwork of a different kind.

Every permit and application I filed had my name, my address, my phone number sitting right there on it.

That information doesn't stay on that form.

Data brokers buy it and sell it, and it ends up with people that you never want to have it.

Today's sponsor Incogni can help with that.

Incogni helps you pull your personal information back out of their hands.

We're talking about real threats like identity theft, scams, and stalking because they can't harm you if they can't find you.

Your home address, phone number, and relative's information are being sold online

and criminals use this data to take out fraudulent loans or track people down in real life.

I signed up for Incogni, gave them the legal right to work on my behalf and then just sat back and relaxed.

It's really that easy.

Their custom removals feature is really cool.

You can flag any website where your data is exposed and they'll get it removed.

I've seen a dramatic drop in where my information is showing up online.

Okay, so back to Australia and how they made solar boring.

Australia's solar dominance took decades to build and almost none of it was about technology.

It was about money and one very weird quirk of how their electricity market works.

There are some, let's say, structural factors that made solar a more enticing option on Australia than America.

First off, the price of energy is just higher there, and

that continues to today. $0.28 per kilowatt hour in Australia is 40%

higher than the average of $0.20 per kilowatt hour here in the US.

The higher the price, the greater the incentive to go with the renewable sources.

I feel the pain.

The cost per kilowatt hour delivered in Massachusetts is over $0.30, which is part why I wanted to go solar myself.

The price is also less predictable.

Retail energy costs skyrocketed in Australia earlier this century.

Their utilities poured money into infrastructure that the grid just didn't need.

The more they built, the more profit they were guaranteed.

It's a bonkers quirk of the Australian utility structure known as gold plating, and it cranked up retail prices.

If your energy price goes up 195% in 15 years, as it did in the state of Victoria,

you're You're going to see Crikey hop in your Land Rover and head to the bush in search of a cheaper alternative.

Or at least something like that.

In response to this really wild energy market, Australia pursued policies aimed squarely at building the consumer market.

It still does.

They made it easier to buy and sell solar panels and batteries.

This began in the early 2000s and as solar prices plummeted during the Great Recession, solar installations took off.

Germany wrote the playbook with the first subsidy scheme.

When Australia copied the German model and ran in a senior climate, Australian energy strategist Dr. Gabriel Kuyper put it plainly, none of us would be here without them.

Australia's version included rebates that sometimes covered the entire cost of the solar panels plus feed-in tariffs

that paid households for the energy that they fed back into the grid.

The national rebate started at $8,000 Australian for a small 1 kW array.

In parts of the country, that was more than the sticker price of the panels themselves.

Critics attacked these schemes as an expensive way to cut emissions, but according to The Guardian, it kick-started an industry of installers,

salespeople, trainers, and inspectors, and quickly made solar a viable option for people beyond the country's wealthiest suburbs.

It was messy and improvised, but it worked.

In the second half of 2025, rooftop solar contributed over 14% of Australia's electricity, a doubling of its contribution from just 2020.

By comparison, small-scale solar contributed less than 2% of US electricity in 2023.

So, I know what you're thinking.

Didn't America have a significant tax credit for solar?

We did.

But we also pursued a policy to promote and protect American solar producers during the 2010s when solar began to take off.

Policymakers had good reason to do this.

This was the Industrial Strategy, a world away from the renewable denialism that dominates the federal government today.

100

In 2011, the US solar industry was dying.

101

China's manufacturing success led to plummeting prices and industry-wide bankruptcy.

102

American manufacturers sued and regulators agreed that Chinese companies had sold panels here for a fraction of their fair market value.

103

A company called Solar World Industries America out of Hillsborough, Oregon filed the petition that started all of this.

104

They got their tariffs, but it didn't save them.

105

The German parent company filed for insolvency in 2017

106

and what was left of the American operation was sold off to a rival the next year.

107

We built the wall and the thing that it was protecting died behind it anyway.

108

There were a variety of policies the government could have turned to, but they chose protectionism.

109

The solar industry lawsuits kicked off four rounds of tariffs targeting solar exports from China and elsewhere between 2012 and 2019.

110

The tariffs helped a handful of manufacturers.

111

They slowed down everybody else.

112

Researchers at the National Bureau of Economic Research found that subsidizing production instead could increase domestic production, employment and welfare.

113

So what would it take for the US to actually catch up on solar?

114

Even if the US could wave a magic wand

115

and replace tariffs with producer subsidies and revive the tax credits that it had just last year, it would still not be on track to catch up with Australia.

116

That's because of the structure of the American incentives and regulations is a mess.

117

Let's start with the incentives.

118

American solar tax credits were annoying to sign up for.

119

You had to apply for them on your taxes after paying the full price upfront, which stops a lot of people from buying them.

120

By contrast, Australia makes it easy.

121

Very easy.

122

Your solar installer automatically deducts your solar credit from your invoice.

123

You don't even have to do anything.

124

Less work for the buyer means more people will buy.

125

So Australia beats us on the incentive design, and then beats us again on the design of the entire system.

126

Or in the American case, the many systems.

127

In Australia and much of the rest of the world, buying solar is like buying any appliance.

128

You call up someone and just get it installed.

129

Bill McKibben laid this out on the Ezra Klein Show.

130

America has around 15,000 separate jurisdictions, and every town and county has its own zoning code and its own team of inspectors.

131

We are tying up solar in so much red tape that the sun can't get to the panels.

132

These rules have neither rhyme nor reason.

133

Illinois requires paper submissions, approved by different departments in a very specific order.

134

Colorado requires paper and online submission, and can spike your application if you don't name your files according to their very specific rules.

135

Remember those panels sitting on my roof waiting on paperwork?

136

This is the machine that kept them there.

137

Look, I love literature, but there's no reason getting panels connected to the grid should be a Kafkaesque nightmare.

138

Combined, these rules slow down solar adoption or stop it entirely.

139

And every one of them carries a price tag.

140

Permit power puts the non-hardware costs of solar in the US, the design, project management, sales,

141

permitting, inspections, and interconnection at a whopping 78% of the total installed cost.

142

This is something I've talked about for years.

143

That tangle of extra rules is costing us big time.

144

Before we start printing Australia t-shirts, I owe you the other half of the story.

145

All that success came with a hangover.

146

When millions of homes push power into the grid at the same moment, midday demand collapses.

147

The Australian energy market operator has been sounding the alarm about minimum operational demand for years.

148

these energy ministers now require backstop mechanisms to be in place for the emergency response.

149

Three different things get blurred together here, so let me pull them apart.

150

The first is the backstop.

151

It's an emergency lever and it only comes out on mild sunny days

152

when there's so much solar that demand on the grid drops dangerously low.

153

The operator can remotely dial back your exports for a few hours and it only applies to newer systems.

154

Your panels keep powering your house the whole time.

155

Fair, boring, and it keeps the lights on.

156

Then there's the second thing, what your exports are worth.

157

Victoria used to guarantee a minimum feed-in tariff.

158

As of July 2025, it doesn't, and retailers set their own rate.

159

The only rule is that it can't go below zero.

160

For context, the last minimum the state ever set was 0.04 cents per kilowatt hour, with a daytime varying rate of exactly zero.

161

Nobody's billing you here, the check just got a lot smaller.

162

Third, South Australia went further.

163

It charges for exporting in the middle of the day, about $1.50 a month, to help pay for the $80 million grid upgrade.

164

That's a fee that's pushing power into a grid that already has too much of it at noon.

165

Whatever you use inside your house is still free.

166

So the deal that built Australian solar, fat rebates and real money for your exports, mostly doesn't exist anymore.

167

Australia solved costs and then ran straight into the next problem, which is a problem I'd love to have.

168

What's left is a country with so much cheap daytime power that the hard problem is soaking it up.

169

And solar does knock off at sundown after all.

170

So home batteries are the sponge.

171

Australia knocked 30% off of the upfront cost in July of 2025 and installs hit $2,000 a day.

172

Same 30% we just threw away.

173

It doesn't have to be this way.

174

The success of solar in Australia comes down to paperwork.

175

The Charged Initiative sent a delegation down there in 2026

176

and they found Australia's low costs are the product of a streamlined permitting, lightweight installation rules and strong audit-based installer accountability.

177

It's boring stuff guys.

178

Boring, achievable stuff.

179

Emissions aside, Americans could be saving so much more with different approaches to solar.

180

And I could show you exactly what that gap looks like because I paid for it.

181

So let me put my own invoice on the table.

182

43 panels, 17.2 kW on my roof.

183

Sticker price? $55,384 before rebates.

184

That works out to about $3.22 a watt.

185

Now price that exact system in Australia, before any rebate, about $15,300 US.

186

89 cents a watt.

187

Then run the incentives on both sides.

188

My federal tax credit and my state credit brought me down to $37,784.

189

And I had to wait until tax season to see a dime of it.

190

The Australian rebate comes off at the the register and brings them down to about $11,200. $55,000 against $15,000 before help.

191

$38,000 against $11,000 after help.

192

Either way, I paid about 3.5 times what the Australian pays for the same panels on the same roof.

193

That's lower than the 7 times you see in the headlines, but 3.5 times is still absurd.

194

Here's the part that should bother you.

195

The subsidies cancel out.

196

Take them away from both countries and the gap is the same.

197

Whatever made my system cost 3.5 times more, a tax credit was never going to fix it.

198

I know where a big chunk of my extra $40,000 went.

199

My installers got most of the panels up

200

and then had to take a bunch of them back down because my town wanted a roughened inspection that nobody knew about.

201

This is something specific to my town, but not unusual.

202

My panels went live in October, but my battery didn't turn on until May.

203

In Australia, you fill out a form online and get approval the next day. $40,000, most of it paperwork and soft costs.

204

Permit power ran the numbers.

205

Reform permitting alone and by 2040 an extra 18.2 million families could install solar.

206

A 155% increase, saving $245 billion.

207

Add in a reduction in tariffs and stop the directly anti-renewable policies of the Trump administration, and America could easily save billions more.

208

Africa is so far and so unnecessarily behind on solar that improvement can seem impossible.

209

But the basic fact is that even explicit anti-renewable policy can't stop the energy transition here.

210

90% of the power added to the grid last year was from renewables.

211

US solar generation has grown every single year since 2006 and there are now 6 million solar installations in this country.

212

There are two real reasons to be optimistic.

213

First, the AI build-out is putting brutal pressure on energy bills.

214

pressure was essential to Australian success.

215

Second, look at Texas.

216

It's the number one solar state in the country and it got there on cost and easy permitting.

217

Deep red state, cheapest electrons in America.

218

Nobody had to win on a culture war.

219

They just made it easy to build.

220

America and Australia both have the sun and the size and both have a fossil fuel industry pushing the other way.

221

America falling behind is a choice and choices can be unmade.

222

And here's my take.

223

This is a paperwork problem and that's what makes this so maddening.

224

Give us one national standard for residential solar instead of 15,000 versions of the same rulebook.

225

Put the permit online and automate the approval.

226

Texas and Australia both show what happens next.

227

Do I think we'll actually do it?

228

Not quickly.

229

15,000 jurisdictions don't hand over control just because it would be cheaper for everyone.

230

But this is the rare problem where we already know the answer.

231

We just have to be bothered enough to do the paperwork about the paperwork.

232

So what do you think America could do to catch up to Australia?

233

What policies would be the most effective?

234

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
