Japan aims to power Tokyo Olympics with 100 percent renewable energy

With the Tokyo Olympics just two years away, the event’s organizing committee has announced it wants to power the games exclusively through renewable energy.

That means building systems to supply the Games — both Olympic and Paralympic — with electricity generated from renewable sources such as wind and solar as part of efforts to promote decarbonization, the Japan Times reported.

Described by an official as “unprecedented” for a major sporting event, the Games’ renewable energy target will also encompass the athletes’ village, the international broadcasting center, and the main press center.

Part of the strategy designed to help it reach its target will involve renting and leasing items that are used during the event. If any need to be bought, the committee will make arrangements to guarantee their use once the sporting extravaganza is over.

Organizers also plan to purchase renewable energy from power companies and to install solar panels where possible.

Speaking of solar panels, the committee is making plans to build a number of solar roads to generate some of the power used by the 2020 Games. Embedded directly in roads, the surface of the panels includes a special resin to ensure their durability, the Independent reported. As part of a trial, a convenience store near Tokyo recently installed solar panels beneath its parking lot, with the setup now taking care of almost 10 percent of the store’s power needs. Similar technology has already been installed in several roads in France, as well as on cycle paths in the Netherlands.

Other efforts to make the games greener include making the medals from precious metals collected from used mobile phones. Organizers launched a campaign in Japan last year to encourage people to recycle their old mobile phones from which the metals can be extracted.

Partnering with Japanese cellular giant NTT Docomo and the Japan Environmental Sanitation Center, the plan is to collect at least eight tons of metal from discarded mobile devices. Millions of phones are needed so that enough material can be gathered to make the 5,000 medals due to be presented at the event in 2020.

Recent Olympic Games have used recycled electronic waste to create the medals, but Japan says Tokyo 2020 is aiming to be the first where all of the gold medals are made entirely with recovered metal.

Yet another study says AI is bad for elections, and the rabbit hole gets worse
AI may be an election bomb waiting for someone to light the fuse
Voters cast their ballots on Election Day

Another election, another study has concluded that asking an AI chatbot for political guidance is a spectacularly bad idea. Research conducted during Hungary’s 2026 parliamentary election found that ChatGPT and Google Gemini offered not just inaccurate but also inconsistent and unreliable voting advice. The chatbots misclassified voter profiles, overlooked relevant parties, recommended parties absent from the ballot, and sometimes produced materially different answers when given the same information repeatedly.

Samsung’s humanoid robot ambitions are real, but factories come first
Samsung’s new robotics division has humanoids in its sights, although its immediate business is far more practical factory automation

Samsung wants a place in the humanoid race, but its new robotics push begins with machines built for factories rather than homes.

The CEO-led RX robotics division will initially focus on manufacturing robots. Samsung has separately identified humanoids as a priority, although it hasn’t announced a commercial model or explained where one fits into the division’s immediate plans.

The future of AI may depend on this one behind-the-scenes change
Running Claude on Android.

Whenever a new AI model arrives, it's easy to get caught up in the bells and whistles. We talk about how much smarter it is, how quickly it answers questions, or how realistic its images have become. But here's the thing: none of that matters much if the AI can't reliably work with the apps and services people use every day.

That's why an upcoming update to the Model Context Protocol (MCP) caught my attention. It isn't a new chatbot or a fancy AI model. In fact, most people will never even know it's happening. But it could quietly make the AI ecosystem a lot healthier. If you've never heard of MCP before, don't worry. Think of it as a shared language that lets AI assistants safely talk to apps like Gmail, Slack, calendars, databases, and countless other services. Instead of every company inventing its own way to make those connections, MCP gives everyone a common rulebook.
