The verbatims: The first climate-tech category consists of low-carbon energy generating machines, including solar panels, wind turbines, and nuclear power plants. These energy sources produce electrical power with minimal carbon emissions. However, they are not problem-free or risk-free. Wind and solar power are intermittent, requiring energy storage (e.g., batteries) and a major grid overhaul. And further down: If solar, wind, and nuclear electricity generators won’t solve the climate problem, and fossil fuels have to be quickly phased out, where will we get our energy? Next paragraph: Instead, we can use energy from sunlight, wind, and flowing water, not just in high-tech ways—via photovoltaics, wind turbines, and hydroelectric dams—but in low-tech ways that entail less usage of mined materials. Low-Tech Magazine explores these options, including human-powered air compressors, sailing ships, practical household bike generators Bit of a far cry from ‘the content is never implied’.
