   In Sweden proposals exist to phase out direct electric heating for this reason (see oil phase-out in Sweden). Nuclear, wind, solar and hydroelectric sources reduce this factor. In contrast, hot-water central heating systems can use water heated in or close to the building using high-efficiency condensing boilers, biofuels, or district heating.

   Bellpuig Solar Park near Lerida, Spain uses pole-mounted 2-axis trackers To maximise the intensity of incoming direct radiation, solar panels should be orientated normal to the sun's rays. [ 61 ] To achieve this, arrays can be designed using two-axis trackers , capable of tracking the sun in its daily movement across the sky, and as its ...

   A solar street light in British Columbia, Canada. The solar panel is one of the most important parts of a solar street light, as the solar panel can convert solar energy into electricity that the lamps can use. There are two types of solar panels commonly used in solar street lights: monocrystalline and polycrystalline. The conversion rate of ...
