    AES’ innovative solutions are transforming the solar sector

    Solar energy is increasingly one of the most cost effective and abundant renewable energy resources in the world. Estimates from BloombergNEF (BNEF) show it is now cheaper to build typical utility-scale PV farms than it is to generate electricity from conventional thermal power stations in Germany, France, Italy, Spain, Portugal, Greece and several more non-EU markets globally[1].

    How AES supports electrification by making electric car adoption easier

    Emissions from passenger vehicles generate a large share of global greenhouse gas emissions and contribute to poor air quality in many urban cities. Switching to electric vehicles (EVs) is necessary to accelerate a cleaner energy future for everyone. The good news is the transition has already started. Many automotive companies are committed to eliminating sales of internal combustion vehicles and to make all vehicles electric in the future.

    Capacity mechanisms: an insurance policy to meet changing electricity demand

    What do thermal power plants provide? Electricity, of course. But that’s not all. They are essential to ensure sufficient capacity. This means having the ability to generate electricity when it is needed. Why is this important? Because demand for electricity varies depending on the time of day and the time of the year. Demand is usually lower at night when people are asleep and higher in the winter when people need to heat their homes. Most of these daily and annual variations are predictable.

    The transition to clean energy: essential but by no means quick and easy

    Energy companies must embrace the transition to clean energy. It is an obligation to future generations AND a business imperative. Any company that does not invest heavily in clean technologies and renewable energy will struggle to survive.

    But the transition cannot – sadly – happen overnight. And ironically, the types of energy we have to shift away from, like coal, can actually support the deployment of renewables in some cases. Traditional energy sources can be a bridge to a clean-energy future.
