Renewable Energy: Answer to Climate Change

Solar Panels in Perth

Solar Panels in PerthIn the words of Wallace Broecker, ‘Climate is an angry beast and we are poking at it with sticks’. At the centre of the climate change debate is the use of fossil fuels and the generation of greenhouse gases. Carbon-neutral energy sources offer a safe bet in conserving the environment.

Solar power is at the forefront of this movement, not only in Australia but in the world. Here are other alternative power sources:

Solar Energy

According to The Australian Renewable Energy Agency, over 2 million households have embraced solar power. Solar energy has been harnessed to produce light via photovoltaic and solar thermal systems. It is safer and more reliable because it is independent of the political stability of countries rich in oil and gas.

Wind Power

The wind carbon dioxide emission per every kilowatt generated in an hour is comparatively lower than fossil fuel. Its emission is estimated to be between 0.02 to 0.04 pounds per kilowatt/hour whereas fossil fuels emit carbon dioxide in the range of 0.6 to 3.6 pounds. From the above estimates, wind power towers above fossils energy in eco-conservation.

Biomass

Contribution to global warming wholly depends on the source of biomass as well as the techniques used to process it for energy production. Sustainable sources will go a long way in limiting carbon dioxide and other greenhouse gases emission. Energy plant sources and organic solid waste are examples of biomass feedstock.

Geothermal Energy

Harnesses heat from the earth core crust by use of wells. Electricity is generated using steam harnessed from the hydrothermal reservoirs. Unlike solar energy, which is chiefly focussed on micro-grids, geothermal energy has been extensively used on the national grid.

Hydropower

This explores energy from water movement, generally from two different elevations. Though considered green energy guided by the 0.1 and 0.5 carbon dioxide emission, it encroaches on other ecological systems and has the potential to destabilise it.

The effects of climate change are devastating, if not life-threatening. Consequently, this calls for sustainable solutions to curtail the production of greenhouse gases by opting for the eco-friendly energy sources such as a solar panel that can be ordered from your local solar power store.
