    Study Notes

    • Climate change is causing water source issues through flooding and desertification (FARAH M. AL-DUWEESH)
    • To live sustainably, renewable energy sources should be used, which are not depletable and include wind, solar, water, and tidal (FARAH M. AL-DUWEESH)
    • Solar energy is a renewable energy source that can be used to provide heat, light, hot water, electricity, and even cooling for homes and businesses (FARAH M. AL-DUWEESH)
    • The sun, a massive star, is the source of solar energy and is about 1.5 x1011 m away from Earth with a diameter of 1.39x109 m and a mass of 2x1030 kg (FARAH M. AL-DUWEESH)
    • Solar energy reaches the Earth's surface as electromagnetic radiation, with about 1,377 W/m2 received in a plane perpendicular to the rays, and about 8.9x1016 W reaching the Earth's surface (FARAH M. AL-DUWEESH)
    • Solar energy can be classified as thermal or electric, with thermal energy used for water heating, and electric energy generated through solar photovoltaics (PV) or concentrated solar power (CSP) (FARAH M. AL-DUWEESH)
    • Solar water heaters, such as evacuated tube collectors, glazed flat plate collectors, and unglazed flat plate collectors, are common ways to use solar energy for water heating (FARAH M. AL-DUWEESH)
    • Solar thermal energy can also be used for cooling through the use of Li-Br or ammonia solutions (FARAH M. AL-DUWEESH)
    • Solar photovoltaics (PV) use semiconductors and the photovoltaic effect to directly convert solar energy into electricity (FARAH M. AL-DUWEESH)
    • Monocrystalline silicon, polycrystalline silicon, and thin film amorphous-silicon are the three types of solar PV cells, with monocrystalline cells being the most efficient and commonly used for household applications (FARAH M. AL-DUWEESH)
    • Concentrated solar power (CSP) uses lenses or mirrors to concentrate sunlight into a smaller area, which is then used to generate electricity through the use of a heat engine (FARAH M. AL-DUWEESH)
    • Solar PV cells are safer than CSP systems as they do not produce high temperatures or require a power plant (FARAH M. AL-DUWEESH)
    • Pros of solar energy include its renewability, lack of emissions, and reduced fossil fuel consumption, while cons include its dependence on sunlight and weather trends (FARAH M. AL-DUWEESH)
