Can Renewable Energy Sources Replace Fossil Fuels

The health of our planet requires that this transition take place as soon as possible.

Can renewable energy sources replace fossil fuels.

Although renewable energy sources are better for the environment they are not as predictable. They typically make enthusiastic claims regarding the potential of their specific technologies. The transition to a renewable energy economy will require multiple levels of change over time. Unfortunately people working on renewable energy technologies tend not to throw critical light on the difficulties and limits.

For now she acknowledges that ending economic dependence on fossil fuels is a work in progress. The issue is not if but when. Yet she maintains a positive outlook. For now she acknowledges that ending economic dependence on fossil fuels is a work in progress.

Rapid progress with renewable electricity technologies has led some commentators to think about the complete replacement of fossil fuels within the broader energy system. The polls indicate that the latent market for renewables in already in place. For example even if we made the switch entirely to electric cars we would likely still need hydrocarbon fuels to mine lithium for the batteries and to run machines with longer lifetimes than cars such as airplanes and ocean going vessels. For example even if we made the switch entirely to electric cars.

However little attention has been given to exploring the limits to renewable energy. But despite more than a century of progress electricity makes up only 20 of the final energy that society uses today and the rate of increase has been the same since the earliest days about two percentage points of final energy share per decade. Western europe has extensive experience with investments in renewable energy sources to replace fossil fuels. The transition to a renewable energy economy will require multiple levels of change over time.

Another problem is that if there was a sudden drought hydroelectric power would reduce too. Fossil fuels are causing pollution global warming disease war and the destruction of animal habitats but new sources of renewable energy such are emerging as non destructive non polluting sources of power. It is commonly assumed that greenhouse gas and energy problems can be solved by switching from fossil fuel sources of energy to renewables.
