energy resources & renewable

These are good reading.

The definition of renewable energy seems clear cut: The sun continues to shine, so solar energy is renewable. The wind continues to blow, so wind turbines churn out renewable power

But industries are now pushing to have a growing number of other technologies categorized as renewable — or at least as environmentally advantageous. They include nuclear power plants and the burning of garbage and even the waste from coal mines.

If a source of electricity already widely used by some utilities — hydropower or nuclear power, for example — is deemed renewable, it allows utilities to meet the new renewable-energy requirements while doing little to add wind or solar power to the electrical grid.
