Build the future of clean energy — then use it to change the world. HumaniWatt is a tycoon-style energy simulation with a heart. Grow a renewable energy company from a single wind turbine and solar farm into a global power network — then decide how much of your profit goes to the planet, and how much goes to people. BUILD A REAL ENERGY GRID Choose from solar farms, wind farms, offshore wind, biomass, nuclear, battery storage, and gas backup — each with realistic capacity, cost, and running costs. Watch your Energy Generation Mix update hour by hour as demand rises and falls, and sell surplus power into five live international markets at changing prices. BALANCE PROFIT AND PURPOSE Every Green Credit you earn can be reinvested in more clean generation, or routed into your Global Development Fund with a single slider. Fund real categories of humanitarian projects — clean water systems, malaria prevention, rural medical centres, schools, hospitals, and more — each with its own cost, upkeep, and lasting Impact score. RESEARCH YOUR WAY TO A GREENER GRID Earn Innovation Points by running efficiently — a day without gas backup, a day above 90% renewable generation, a day with zero blackouts — and spend them on a five-tier technology tree: better solar cells, larger turbines, advanced batteries, advanced nuclear, and hydrogen storage. INVEST IN PRESTIGE LANDMARKS Buy iconic landmark assets around the world as long-term income investments, funding even bigger humanitarian projects down the line. TRACK EVERYTHING A full company balance sheet, Past Day and Past Week history charts, a notifications feed, and a live world-impact scoreboard (people helped, schools built, hospitals funded, clean-water projects delivered) keep your progress visible at every level.
