Renewable energy sources have emerged as a crucial solution to reduce dependency on non-renewable sources such as fossil fuels. This shift is driven by several factors, including environmental concerns, energy security, and economic advantages. Here are some ways in which renewable sources decrease dependence on non-renewable sources:   Environmental Sustainability: One of the most compelling reasons to transition to renewable energy is its minimal environmental impact compared to fossil fuels. Burning coal, oil,... more

Currently, solar energy is considered an efficient and environmentally friendly option. Its efficiency varies depending on the area you live in. For example, if you live in a cloudy location, you can still use solar panels to generate electricity, but the efficiency will decrease by about 10 to 25 percent. Those living in a region with low sun exposure should plan their installations accordingly. They should consider battery backup in case the sun does not shine for a long time. There are many types of solar energy systems and tec... more

Passive solar design and construction has been used to collect heat from the Sun for centuries. Old buildings, for example, often contain passive solar features such as strategically oriented south-facing walls, large windows, and masonry walls that collect and distribute the heat from the sun. Using these techniques can result in more energy savings in the long run. Active solar energy examples include solar thermal collectors, which use absorption of sunlight to produce heat. These devices can be used for decades without requiri... more
