Dr Noor Fatima (Energy Expert): The signing of agreement with Chinese company to transform a power plant from thermal to solar will help produce cheaper energy. We have already been using gas and other sources to produce energy in the country. It is vital that per unit cost of electricity is brought down not only for households but also for the industrial sector. We need to invest more on renewable sources in order to meet the growing demand of energy in the country. Solar energy is a very big resource for Pakistan because of ample sunshine.
