We rarely think about the energy systems that prop up our existence. With hot water, lighting and digital entertainment all available at the flick of a switch, it's easy to underestimate the vast global network that makes these things possible.

Growing up in Iraq, Yasmin Ali regularly experienced power cuts - ironic for a country rich in oil and sunshine. Now as an engineer working in energy, Yasmin has a deep appreciation for what these resources mean for our lives.

In Power Up she takes us on a journey across the globe to reveal the bigger picture, from solar farms shimmering in the desert to power stations hidden deep in the mountains. We discover where we get energy from, how it is moved and used around the world - and why we need to understand the whole system if we want to transition towards a clean, green future.

Power Up is a definitive picture of the intricate world that humanity has built, and a rallying cry to face the challenges of climate change using the power at our fingertips.

Growing up in Iraq, Yasmin Ali and her family regularly experienced power cuts - ironic for a country rich in oil and sunshine. Her journey out of Iraq with her family is a story powered by fossil fuels - planes, cars and trains are what transported them to safety. Now as an engineer in the energy sector with a deep appreciation for what these resources mean for our lives, Yasmin shows us just how much energy underpins our world and connects disparate landscapes and people. In Power Up Yasmin invites readers to discover a vast global network of power stations, gas pipelines, transmission cables, and engineers, quietly working behind the scenes and spanning the world. Her book traces a journey, from energy source as coal, oil and gas, nuclear or renewables, through cables and pipelines, or on ships and trucks, around and across the world and into our individual homes, powering our modern lives. At a time when climate change and the transition to clean energy are high up the agenda, Yasmin shines a light on our energy use and looks to the future to imagine how our world could be powered. Every person on this planet, whether we live in a bustling city like New York or a remote community in New Zealand, depends on energy. Power Up remind us that we are all bound by the same resources on this planet, and that the energy crisis is a global problem that requires global solutions.
