Green buildings also use renewables energy, which can be cheaper than fossil fuel alternatives. ... Renewable energy also has the additional benefit of producing no carbon emissions, limiting the impact on the planet. Energy efficiency coupled with local renewable sources also improves energy security.

Tidal power is an environmentally friendly energy source. In addition to being a renewable energy, it does not emit any climate gases and does not take up a lot of space. However, there are currently very few examples from real tidal power plants and their effects on the enviroment.

Common effects include decreased water quality, increased pollution and greenhouse gas emissions, depletion of natural resources and contribution to global climate change. Some of these are the direct result of human activities, whereas others are secondary effects that are part of a series of actions and reactions.

Human Impacts on the Environment. Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

The environmental effects of geothermal development and power generation include the changes in land use associated with exploration and plant construction, noise and sight pollution, the discharge of water and gases, the production of foul odours, and soil subsidence.

As with all energy supply options, wind energy can have adverse environmental impacts, including the potential to reduce, fragment, or degrade habitat for wildlife, fish, and plants. Furthermore, spinning turbine blades can pose a threat to flying wildlife like birds and bats.

Here are a few of the ways that technology can harm the environment: Pollution - Air, water, heat and noise pollution can all be caused by producing and using technology. Consuming resources - Non-renewable resources, including precious metals like gold, are used to make technology.
