简介

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.

非可再生能源

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 , 自然气体.

可持续能源

可持续能源具有长期可用性,将满足当前和未来的需求。 他们还补充自己,而且高效节能,(我们得到了更多的能量了,比我们投入生产的话)。

例子包括: 核聚变生活垃圾燃烧(清洁).

可再生能源

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.

可再生能源的实例包括 生物质能, 地热,水电,氢, 海浪潮汐, 江水流, 太阳的.

能源效率

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.

能源独立

能源独立是另一个能源问题。 大多数国家的政府非常希望成为能源独立,而不是需要从其他国家的能源供应。 例如,美国宁愿它是不依赖于其他国家的石油。

节约能源

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.
