Greenpeace is an independent global campaigning organisation that acts to change attitudes and behaviour, to protect and conserve the environment and to promote peace.

Greenpeace is present in more than 55 countries across Europe, the Americas, Asia, Africa and the Pacific.

To maintain its independence, Greenpeace does not accept donations from governments or corporations but relies on contributions from individual supporters and foundation grants.

Why do we need to change the way energy is produced and used? Let me count the ways…

The current energy system results in:

1.Climate change2.Public health issues3.Water scarcity and pollution4.Energy insecurity and war5.Oil spills6.Air pollution7.Acid mine drainage8.Rising and unpredictable costs9.Nuclear accidents/waste disposal problems10.Etc…

Avoiding catastrophic climate change means staying below 2o C

- Global GHG emissions must decrease by at least 80% by 2050

- To get there, energy sector (electricity, heating and transport) must be decarbonized

Is 100% renewable energy possible?RE Final Energy share: 2012: 19% // 2020: 23% // 2030: 42% // 2050: 100%

How to get to 100% renewable energy by 2050

1. Phase out fossil fuels- Lignite (2035), coal (2045), oil and

gas (2050)2. Phase out nuclear (2050)3. Reduce energy demand (15% below current levels)4. Increase renewables

- Solar PV, Wind (8,040 GW), CSP, hydropower, geothermal, ocean, hydrogen, synthetic fuels, biomass/biofuels5. Electrify large portion of heating (19+%) and transport demand (53%)6. Build a smart grid, rely on energy storage, and reform energy markets

Benefits of 100% power sector:

1.Money: Fuel costs savings means 100% RE is less expensive than BAU

2.Jobs: Greater employment and economic development opportunities

3.Safe climate: Only way to stay below 2 degrees C warming

Climate

100% renewable energy by 2050 is:

1. Technically and economically achievable

2. Only way to avoid catastrophic climate change

3. Will result in more jobs in the energy sector

4. Less expensive overall than business-as-usual

5. A ready solution for access issues and energy supply shortages
