Green energy provides real benefits for the environment since the power comes from natural resources such as sunlight, wind and water. However, the same can be said of solar panels, which are also seeing a great deal of development. Green energy solutions also have the benefit of not needing much additional energy expenditure after they have been built, since they tend to use a readily renewable source of power, such as the wind. Green energy can also lead to stable energy prices as these sources are often produced locally and are not as affected by geopolitical crisis, price spikes or supply chain disruptions. Student exploration energy conversion in a system answer key pdf answers free. Describe the different forms of energy. Green energy is that which comes from natural sources, such as the sun.
