Many power systems at present make use of renewable sources, most commonly hydro and wind power. For now it is sufficient to note that, as mentioned earlier, geographical diversity of the wind resources assists integration. Geographical diversity also applies to the other renewable resources and is important to their integration into power systems. The relationship between the different renewable sources, spatially and temporally, is also directly relevant to the issue of integration. Tidal current velocities are not correlated with wind speeds, and wave energy, although an integrated form of wind energy, is not strongly correlated with ten minute or even hourly wind speeds. Solar power has its own unique pattern of variation, and biomass is flexible. How renewable sources of generation can be combined to meet load demand is a critical issue and is discussed in later parts of the book.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
