![]() ![]() From " Is there gravity on the moon?" to " What is the biggest known star in the universe?" to " Where do pandas live?", we're striving to find answers to the most common questions you ask every day. USA TODAY is exploring the questions you and others ask every day. Just Curious for more? We've got you covered Other examples of renewable energy include wind energy, geothermal energy, hydropower, ocean energy and bioenergy, according to the United Nations. ![]() Solar power can also be converted into thermal or electrical energy. In fact, it is " the cleanest and most abundant renewable energy source available," according to the Solar Energy Industries Association. How hot is the sun? Get to know the blistering temperatures of the star's surface, core Is solar energy renewable? The amount of electricity generated is dependent on how many cells are in each panel: The more PV cells, the more electricity. The electricity is then collected through the negative and positive sides of the cell and flows out. When sunlight hits the PV cell, it releases electrons from the semiconductors. A group of solar panels is called a "solar array." Each cell is made of semiconductor material containing negative and positive receptors, similar to a battery. Solar panels are made of several PV cells, and each produces about one to two watts of power, according to the Office of Energy Efficiency and Renewable Energy. When sunlight radiates to the Earth and onto a solar panel, the energy is absorbed. Photons are found in sunlight, which is a form of electromagnetic radiation. The amount of sunlight that reaches the Earth's surface every hour and 30 minutes is enough to power our planet for a year, according to the Office of Energy Efficiency and Renewable Energy. Solar panels, also known as PV panels, convert sunlight into electrical energy. Solar energy is responsible for sustaining many things, including weather, wind and plant and animal life. This heat, light and energy are all forms of electromagnetic radiation, according to National Geographic. The solar energy that is created is released in the form of waves and particles, which move from the sun throughout the solar system. As these molecules merge, energy is released from the leftover mass. ![]() ![]() This collision has great enough force to form a new element: helium. In the sun's core, hydrogen molecules will collide due to the immense pressure and density. Nuclear fusion is a reaction that occurs in the sun and other stars and creates energy. It is created through a process called nuclear fusion. Solar energy is energy that comes from the sun. Through different technologies, such as solar panels, solar energy can be converted to generate power.īut how do solar panels work? Here is what you need to about solar energy and photovoltaic, or PV, technology. Thanks to the Sun, life on Earth continues. One of the major sources for energy on Earth is the Sun. Each has its own properties and fuel processes that make aspects of life possible, including driving a car or burning a fire. From kinetic and potential to chemical and sound, various forms of energy exist on our planet. ![]()
