As concerns about climate change continue to grow, there is a growing focus on developing clean energy technologies. By 2050, it is likely that renewable energy sources such as solar and wind power will be much more efficient and affordable, leading to a significant reduction in carbon emissions. This could also lead to new opportunities for energy storage and distribution, such as batteries and smart grids. Internet of Things (IoT) Virtual reality (VR) and augmented reality (AR) technologies are changing the way we interact with the world around us. VR enables users to enter a fully immersive digital environment, while AR overlays digital information onto the real world. These technologies have many applications, from entertainment and gaming to education and training.
