What to watch for [Passengers arrive from New Zealand after the Trans-Tasman travel bubble opened overnight, at Sydney Airport] Reuters/Loren Elliott After several delays, a relatively [unrestricted travel bubble launched today]( between two of the worldâs most Covid-19 cautious countries, Australia and New Zealand. Thanks to minimal cases, the New Zealand-Australia bubble wonât involve mandatory testing, proof of vaccination, or quarantines, in a bid to try and recoup some of their pre-Covid travel. Bubbles are far more helpful toward restarting travel than one-way relaxations of the sort Australia extended to New Zealand last year. While the latter might work just fine for a citizen trying to return home and stay put, leisure travel requires both being able to leave and return just as easily. Still, a bubble is exactly what it sounds like: fragile and liable to pop at any moment, which could lead to an abrupt and costly end to trips for passengersâa risk both would-be travelers and the industry must monitor. As New Zealand prime minister Jacinda Ardern has said: flyer beware. Charting why small businesses actually matter Small businesses that stay smallâfewer than 100 employeesâarenât efficient, according to key metrics. [Unemployment in the US, broken down by business size.] Small businesses tend to pay their employees less, provide them less generous benefits, and offer fewer opportunities for advancement compared to larger enterprises. Small businesses arenât as productive as big businessesâitâs called economy of scale for a reason. Heck, most small businesses donât even last that long. So why do we prefer them, both anecdotally and in our neighborhoods? It turns out our reasons for encouraging small businesses that pay less and and last a short time might be more social than economic, writes Tim Fernholz: People insert local businesses when they describe the neighborhood of their dreams, and surveys of downtowns that are consistently rated the best in the US find that they [boast a preponderance of independent firms](. Taking the long view on solar energy Last August, Spanish solar developer Enerland offered to sell electricity for â¬11.14 (US$13.12) per megawatt-hour (MWh), one of the lowest auctioned electricity prices in history. One megawatt hour is slightly more than the average home in the US consumes per month. Sellers undercutting themselves in Portugal arenât throwing their money away, however. Theyâre betting the superior economics of solar power, and a coveted connection to the countryâs crowded electricity grid, will cover any losses over the first 15 years before firms are free to sell power at market rates. Developers are willing to pay big money to sell cheap power into the grid. As renewable energy prices drop even further, says Jenny Chase, who leads solar analysis for BNEF, developers will find innovative ways to bring wholesale electricity prices even lower and [return those savings to the grid](. ⦠Concerned about climate change?
