We’ll often see headlines quoting how many gigawatts of new solar farms or coal plants China is building. But it’s hard to get a meaningful sense of scale for how electricity generation in China is changing.<br>The chart puts it in perspective.<br>In 2025 alone, China’s electricity generation increased by almost 500 terawatt-hours (TWh). This is compared here to the total amount of electricity that whole countries generate each year.<br>Germany generates almost exactly that amount. That means China effectively added a Germany-sized grid to its electricity system in just one year.<br>What’s also quite staggering is that almost all of this new generation came from solar and wind. China generated 340 TWh more electricity from solar than the year before.<br>That’s more than our two home countries, the UK and Spain, generate from all sources each year.<br>Low-carbon sources grew so much that coal power in China actually fell slightly.<br>This data comes from Ember’s latest global electricity review — you can explore more of this data on our site.

The chart places this figure in context by comparing it with other countries with data for the same year.<br>Nicaragua and Honduras receive remittances worth around a quarter of their GDP — high by global standards, but still far below Tajikistan's level.<br>Remittances here include two types of flows: money migrants abroad send home to their families, and money cross-border workers bring home from short-term jobs abroad.<br>Both of these flows play a role in Tajikistan, where most remittances come from labor migrants in Russia. In addition to the roughly 400,000 Tajiks settled there, hundreds of thousands more cross the border for seasonal and short-term work. According to a report from the International Organization for Migration, about 1.2 million Tajiks were in Russia in mid-2024, which is more than a tenth of Tajikistan's total population.<br>The World Bank's latest Tajikistan Economic Update says that much of the country's recent rapid economic growth (above 8% since 2021) was supported by these remittance inflows.<br>Explore interactive data on remittances for all countries.

May 14<br>Japan closed nearly all of its nuclear plants after Fukushima, but some are coming back online<br>Japan closed down most of its nuclear plants after the Fukushima Daiichi disaster in 2011, and nuclear production dropped dramatically.<br>You can see this in the chart above, which shows Japan's electricity mix since 1985. It’s based on data from the Energy Institute.<br>Fossil fuel plants — notably coal and gas — were ramped up to keep the lights on. The first nuclear reactors only came back online in 2015, under stricter rules from a new safety regulator created after the disaster.<br>As of early 2026, 15 reactors are running — out of 54 before Fukushima — and nuclear's share of electricity is still only around a third of its pre-2011 level.<br>Read our article on the death toll of the Fukushima and Chernobyl disasters

May 12<br>Cereal yields in Ghana have increased much faster over the past decade<br>Crop yields across Africa have lagged far behind the rest of the world — the regional average is around 2.5 times lower than the global average.<br>But some countries in the region show that yields can grow much faster. Ghana is one example. In the chart, you can see its cereal yields compared to the average for Africa as a whole.<br>Several government programs contributed to this growth.<br>In 2008, the Ghanaian government launched a fertilizer subsidy program; it had some impact on yields but was relatively modest.<br>The largest shift came from the introduction of the Planting for Food and Jobs program in 2017, which dedicated large public funds to distributing improved seeds, fertilizers, and other inputs to farmers.<br>The data shown is based on nationally reported statistics, and some researchers question the exact size of the reported gains.<br>But the result that yields have gone up looks robust: independent modeled assessments estimate that maize and rice production are over 40% higher than they would have been without the program.<br>Read my article on why increasing agricultural productivity in Sub-Saharan Africa is one of today’s most important challenges.
