4. Independent of electricity prices
4.1. With solar power, it's possible to avoid the rise in price of power plants which differs through the day, and get cheap energy all day
5. Causes less electricity loss
5.1. The longer energy has to be transported, the more energy is wasted on the way
5.1.1. The longer energy has to be transported, the more energy is wasted on the way
5.1.2. The longer energy has to be transported, the more energy is wasted on the way
5.2. direct curent -> less lost elec than alternative current
6. Durable
6.1. They require little maintenance and have a long lifespan
7. Cost and benefit
7.1. Beyond the initial installation and panel costs, solar energy is free. This means that your solar panels will eventually pay for themselves and you can typically start earning from solar panels 10-15 years after initial installation

12.3.2. Interventions in nature due to damming of water, changed water flow
12.4. Expensive
12.4.1. Building power plants in general is expensive. Hydroelectric power plants are not an exception to this
12.5. Limited Reservoirs
12.6. Droughts
12.6.1. Electricity generation are directly related to how much water is available. A drought could potentially affect this
