On today’s show, we’ll explore some useful devices that make use of solar energy to perform a variety of functions in daily life. The Sun constantly radiates its loving energy into the cosmos, and nowadays, technological advances are allowing us to make use of its energy to operate a wide array of practical gadgets. For example, solar panels covert sunlight into electricity by means of photovoltaic cells, and photoelectrochemical cells use artificial photosynthesis to convert sunlight into solar energy. Many small devices or tools powered by the Sun have also emerged on the market, making this free green energy more accessible to everyone.

Today we’ll examine the problem of global waste and learn how to live a zero-waste lifestyle. Everyone sees we have a problem with plastic, and everyone knows we need to solve it. And it’s urgent. Everyone knows that if we don’t do something about this, plastic will suffocate our oceans, will cause ever-worse health problems for human beings.We need to do something about this. We cannot keep giving poison to the Earth because it will stay in the soil forever and keep building up generation after generation. We should do what we can to minimize harm to the environment because that’s our duty. We should do that, we should be kind.
