The essentials of energy and climate in five short reads: how forests store carbon, how solar farms reach the grid, why wind makes power cheap at some hours, why heatwaves bring power cuts and why sea levels rise unevenly.



Part 1How forests store carbon, and how they lose itTrees pull carbon from the air as they grow, but fire and felling can release it again.
Part 2How a solar farm sends power into the gridPanels make direct current; inverters, transformers and grid operators do the rest.
Part 3Why electricity is cheaper at some hours when the wind blowsWhen wind is strong and demand is low, power prices can fall sharply — sometimes below zero.
Part 4Why power cuts happen more on the hottest daysDemand spikes just as heat makes lines and transformers less able to cope.
Part 5Why sea levels don't rise evenly around the worldGravity, currents and sinking land mean some coasts see far more change than others.
