Describe A new law you would like to introduce in your country

If I could roll out one new law in China, it would be a mandatory rooftop solar regulation requiring all newly built residential and commercial properties to install photovoltaic systems on their roofs, backed by a 30% government subsidy for upfront costs and a guaranteed feed-in tariff for excess power fed back to the grid. The most transformative change would be a steep drop in building-related carbon emissions, which currently make up roughly 40% of China’s total carbon footprint, as solar power replaces coal-fired electricity for daytime consumption. It would also ease strain on the national power grid during summer peak hours, when surging air conditioning use often triggers localised blackouts. I believe this law would be broadly popular. Homeowners and business operators would slash their long-term utility bills, and the domestic photovoltaic sector would see a surge in high-skilled jobs. While some developers might grumble about extra construction steps, the subsidy would offset most additional expenses. Personally, I find this policy incredibly forward-thinking: it’s a tangible, actionable step to tackle climate change while boosting the green economy, which feels both urgent and deeply meaningful.
