Could a Pay-as-You-Go Model Convince People to Go Solar?

Simpa Networks' Paul Needham thinks the key to selling solar power is asking customers to pay for it as they use it.

Paul Needham is interested in why and how people buy things. As a doctoral student at Cambridge, he specialized in a field of economics that asked questions like “What does it cost a buyer to find a seller?” Does the buyer have to travel a great distance, for instance? Does she have to pay a fee to a middle man? So when he started thinking about energy access—how to improve the way people in places without strong electricity infrastructure get their power—one of the questions he asked himself was “Why don’t I own solar panels?”

His answer was that panels cost too much up front. Installing them made the most sense, he says, when he thought about the way he paid his phone bills, in monthly increments of about $100, which would add up over five years to $6,000.

“I would never pay $6,000 up front for a phone that gave me free calls for 5 years or 10 years or 20 years,” he says. “I wouldn’t do it, even if I thought I’d be better off.”

But that’s what solar companies essentially ask customers to do: pay up front for electricity years into the future. For very poor people with irregular incomes, that doesn’t make sense. Simpa Networks, the company that Needham heads, is working towards offering an alternative. Customers put down a deposit for the solar panels, then pay for incremental units of electricity, the same way they might put minutes on their phone.

Simpa Networks is starting by working with solar installers already peddling panels in India. Right now, those companies tend to work with banks to offer potential customers loans in order to finance the cost of owning the system. But Needham thinks that’s the wrong approach for customers who currently rely on energy sources like kerosene. For anyone on an irregular income, kerosene has one advantage: you pay as you go.

Needham argues that companies need to price solar power correctly, not merely offer the right financing plan for the solar system. “What people really want is the service. Let's price for the service,” he says. Simpa pegged its prices to the costs of kerosene: it costs the same amount to light one room with its solar system as it does to light it with a kerosene lamp, and Simpa’s light is brighter.

The company also offers the “nice twist” of putting customers' incremental payments toward ownership, pricing it so that customers can own the panels within 12 to 36 months, a much shorter payback period than solar owners in the United States face. In the end, it’ll cost Simpa’s customers 30 percent more to own the system than if they buy it outright. Simpa’s system, though, offers flexibility and no commitment—customers can return the panels at any time and have their deposit refunded.

That policy is intended in part to help “make good customers,” Needham says. He’s less worried about people switching back to kerosene or other sources of fuel than selling the panels for cash or breaking them down for parts if they hit a rough financial patch. The company is also looking to tap into the group dynamics that have ensured that microlending customers repay their loans. Simpa might offer group purchasing, for instance, or group rewards. If a group spends a certain amount each month, a portion of their payments could go towards a community institution, like a temple or a school.

Although there are a host of companies and nonprofits that are working on different ways to get solar power to people living without reliable access to electricity, Needham is betting he’s found the right solution. Strategies that focus on solar technology, he says, forgot the reality of the consumer, who cares mostly that they have light, not how they get it.

“If I’m a consumer, I don’t care about the technology,” he says. “I just want to pay for the service, as I use the service.”

The World Health Organization is hoping to drive down the cost of insulin by encouraging more generic drug makers to enter the market.

The organization hopes that by increasing competition for insulin, drug manufacturers will be forced to lower their prices.

Currently, only three companies dominate the world insulin market, Eli Lilly, Novo Nordisk and Sanofi. Over the past three decades they've worked to drastically increase the price of the drug, leading to an insulin availability crisis in some places.

In the United States, the price of insulin has increased from $35 a vial to $275 over the past two decades.

Oh, irony. You are having quite a day.

The Italian region of Veneto, which includes the city of Venice, is currently experiencing historic flooding. Venice Mayor Luigi Brugnaro has stated that the flooding is a direct result of climate change, with the tide measuring the highest level in 50 years. The city (which is actually a collection of 100 islands in a lagoon—hence its famous canal streets), is no stranger to regular flooding, but is currently on the brink of declaring a state of emergency as waters refuse to recede.

Since the International Whaling Commission banned commercial whaling in 1986, whale populations have been steadily recovering. However, whales in the wild still face other dangers. In the summer of 2018, four Russian companies that supply aquariums with marine animals captured almost 100 beluga whales and killer whales (aka orcas). After a public outcry, those whales are swimming free as the last of the captive whales have been released, the first time this many captured whales have been released back into the wild.

In late 2018 and early 2019, a drone captured footage of 11 orcas and 87 beluga whales crammed into holding pens in the Srednyaya Bay. The so-called "whale jail" made headlines, and authorities began to investigate their potentially illegal capture.

The NRA likes to diminish the role that guns play in fatal shootings by saying, "Guns don't kill people, people kill people."

Which is the same logic as, "Hammers don't build roofs, people build roofs." No duh. But it'd be nearly impossible to build a roof without a hammer.

So, shouldn't the people who manufacture guns share some responsibility when they are used for the purpose they're made: killing people? Especially when the manufacturers market the weapon for that exact purpose?

The 2020 election is a year away, but Donald Trump has some serious ground to cover if he doesn't want it to be a historical blowout.

A Washington Post- ABC News poll released Tuesday shows that Trump loses by double digits to the top Democratic contenders.

Vice President Joe Biden (56%-39%); Sen. Elizabeth Warren of Massachusetts (54%-39%); Sen. Bernie Sanders of Vermont (56%-39%); South Bend, Indiana, Mayor Pete Buttigieg (52%-41%); and Sen. Kamala Harris of California (52%-41%) all have big leads over the president.
