What is Solar Heating?

SunlightNaturally the term ‘solar’ means ‘from the sun’. Since the world began it has been used for heat and light. Solar energy can be used throughout the home in a variety of ways. When machinery is used to convert that energy it is known as ‘active’ solar power. However, it can also be ‘passive’, meaning the sun basically shines on a certain place and heats it up. Solar heating in the home can involve having a solar hot water system or passive solar water heater. However, it might just involve preheating the air in the house to comfortable temperatures; houses can be designed in specific ways to make this more efficient. More advanced options of solar heating systems might be using solar panels for electricity.

Solar energy is a renewable energy source as opposed to fossil fuels, such as oil and coal, which are not renewable. However, fossil fuels have been historically cheaper to use. While passive solar heating systems have been used in houses for decades, such as sky lights and passive solar water heaters, the technology for using active solar heating has been expensive. This price is reducing greatly as technology improves and more people begin to use solar electricity. People have also begun to make homemade solar water heaters and panels.
