In 2015 the United Nations announced a radical plan to change the world.

Global leaders drew up a list of 17 "sustainable development goals" to create a blueprint for a better future. Governments agreed to support the goals which cover gender equality, health provision, a good education and much more. Now 17-year-olds from 17 different countries tell us what they think needs to change if the world is to meet those goals by 2030.

Nestor lives in the far north of Colombia and his village has been transformed since solar panels were brought in to provide electricity to the schools. Children now have access to computers, and light in their classrooms. He wants to find out just how much of Colombia's electricity can be created using renewable sources. He visits the country's biggest solar plant, and interviews Colombia's deputy energy minister to find out whether the government will meet the UN goal on clean energy by 2030.
