What is sustainable energy? (with photos)

Wind farms are used to generate sustainable energy.

Sustainable energy is energy that can potentially be maintained in the future without causing harmful repercussions for future generations. Various types of energy can be considered sustainable and many governments promote their use and the development of new technologies that fit this model. Rising rates of energy consumption around the world have led to a corresponding increase in concerns about where energy comes from and whether it will become scarcer.

Several factors contribute to making energy sustainable. The first is whether current energy use is something that could persist into the future, which leads many forms of renewable energy to qualify as sustainable. People can generate energy from windmills, ocean waves and the sun without running out of energy and resources, making these methods sustainable for use by future generations. In contrast, fossil fuels are not treated as sustainable because Earth’s crude oil supplies will run out.

Solar panels use energy from the sun, making them a sustainable energy source.

Another consideration is energy efficiency. Some forms of renewable energy, for example, require a lot of effort to actually generate, meaning that almost as much energy goes into their production as the sources themselves generate. Energy efficiency can also be used to describe technologies that use energy, such as homes, cars, and businesses. Increasing efficiency in the way energy is used makes sustainable energy spread even further.

Many people also think that the environmental impact of an energy source is another facet of its sustainability or not, which is why sources like nuclear are often not treated as such. While meeting the demands of renewability and energy efficiency, nuclear energy can have a negative impact on the environment. Likewise, some of the methods used to produce solar panels, wind turbines, and other technologies to convert renewable sources into energy are polluting, leading to concerns that such technology will just transfer the pollution to a different place, making it unsustainable.

Another important factor for some people in the energy field is independence. Some critics argue that energy is not sustainable if a nation is forced to rely on another country to meet its energy needs, even if that energy is renewable, non-polluting and efficient. For example, if the United States relied heavily on Canadian wind farms, this would violate the energy independence criterion. Being able to meet your own energy needs as a nation is an important part of sustainable energy in the eyes of some people who are concerned about the intersection of energy and politics.
