Introduction

Energy is arguably one of the most important environmental topics to date. Although it is an important environmental issue entirely on its own, directly or indirectly, energy relates in some form to all environmental issues and concerns. Take urban planning for example. Direct involvement derives from the amount and type of energy source required to heat an office building. Indirect involvement includes the preliminary designs associated with choosing a geographically desirable location where homes and stores are in the near proximity to reduce a high consumption of energy typically required in commuting.

Listed below are important ideas that provide a basic understanding concerning energy, the focus of the IEA.

Sources d'énergie non renouvelables

Non-renewable energy sources cannot be produced or used on a scale sustainable for future generations. Therefore, these energy sources can be completely depleted.

Examples of non-renewable energy sources include fossil fuels such as pétrole, charbon et des gaz naturels.

Sources d'énergie durables

Sources d'énergie durables ont disponibilité à long terme qui répondra aux besoins actuels et futurs. Ils reconstituent aussi sur leur propre et sont économes en énergie, (nous recevons beaucoup plus d'énergie que ce que nous mettons dans sa production).

Les exemples incluent la fusion nucléaire et combustion des ordures ménagères (nettoyage).

Sources d'énergie renouvelables

Renewable energy sources are those that meet the same requirements as sustainable energy sources, with an additional responsibility to leave minimal impact on the planet. They do not pollute the environment and ecosystems, and lessen global warming. If an energy source is renewable, it is automatically sustainable.

Des exemples de sources d'énergie renouvelables comprennent la biomasse, géothermique, hydroélectrique, de l'hydrogène, vagues de l'océan et marées, courants rivière, solaire, et Vent.

L'efficacité énergétique

Energy efficiency is important when discussing renewable energy. In some cases, even though a new and interesting energy source is researched and proven sustainable, it may require almost as much energy to produce the sustainable energy as the sustainable source generates. Energy efficiency is not a new term and is used to describe many traditional technologies such as home insulation and car fuel efficiency.

L'indépendance énergétique

L'indépendance énergétique est un autre problème de l'énergie. La plupart des gouvernements aimeraient beaucoup d'énergie pour être indépendant, et ne pas exiger l'approvisionnement en énergie à partir d'autres pays. Par exemple, les États-Unis plutôt que ce n'était pas dépendre des autres nations pour le pétrole.

Conservation de l'énergie

Energy conservation is especially important when using non-renewable energy sources. Essentially, conserving these resources will enable them to last longer. Somewhat less obvious and often overlooked is the fact that these sources create harmful greenhouse gases and acid rain. Conservation can be important for renewable energy sources as well. For Although hydroelectric power is generated from a dam and renewable, building a new dam can cause massive environmental changes upstream.
