Your Questions About Renewable Energy Definition

Linda asks…

Is tidal Power tiddle power compared to the power of the Nukes Industry?

Slim Footwear (Greenpeace) responding to Chris Hulme’s announcement that 8 Nuclear Power Stations are to be built and the Green Energy tidal generation plans will be scrapped.
“Lib Dem voters backed a party that supported renewable energy and opposed taxpayer handouts to the nuclear industry..”

admin answers:

It depends largely on how you cost the two proposals. If you ignore the cost of decomissioning and waste treatment, then nuclear power is more economical.

If however, you factor in the cost of decomissioning and treatment of waste – the case for nuclear power becomes very, very difficult to support. That’s just the financial cost – there’s also human costs as regards unwanted land use.

Tidal power – by definition – does not take up any land, other than to manufacture the equipment.

This is very disappointing.

Paul asks…

What is the difference between renewable and sustainable energy sources?

Can something be sustainable but not renewable?

admin answers:

Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides, and geothermal heat—which are renewable (naturally replenished)Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Each of these sources has unique characteristics which influence how and where they are used.

Sustainable energy sources are most often regarded as including all renewable sources, such as biofuels, solar power, wind power, wave power, geothermal power and tidal power. It usually also includes technologies that improve energy efficiency
