Switching to clean energy will take a massive social change

Global climate change, driven by human emissions of greenhouse gases, is already affecting the planet, with more heatwaves, droughts, wildfires and floods, and accelerating sea-level rise.

Devastating impacts on our environment, health, social justice, food production, coastal city infrastructure and economies cannot be avoided if we maintain a slow and steady transition to a zero-carbon society.

According to Stefan Rahmstorf, Head of Earth System Analysis at the Potsdam Institute for Climate Impact Research, we need an emergency response.

A big part of this response needs to be transforming the energy sector, the principal contributor to global warming in Australia and many other developed countries.

Many groups have put forward ideas to transition the energy sector away from carbon. But what are the key ingredients?

Technology is the easy bit
At first glance the solution appears straightforward. Most of the technologies and skills we need – renewable energy, energy efficiency, a new transmission line, railways, cycleways, urban design – are commercially available and affordable. In theory these could be scaled up rapidly.

But in practice there are several big, non-technical barriers. These include politics dominated by vested interests, culture, and institutions (organizational structures, laws, and regulations).Greenpeace activists demonstrating

Vested interests include the fossil fuel industry, electricity sector, aluminum smelting, concrete, steel and motor vehicles. Governments that receive taxation revenue and political donations from vested interests are reluctant to act effectively.

To overcome this barrier, we need strong and growing pressure from the climate action movement.

There are numerous examples of nonviolent social change movements the climate movement can learn from. Examples include the Indian freedom struggle led by Gandhi; the African-American civil rights movement led by Martin Luther King Jr; the Philippine People Power Revolution; and the unsuccessful Burmese uprising of 1988-90.

Several authors, including Australian climate scientist Matthew England, point out that nations made rapid socioeconomic changes during wartime and that such an approach could be relevant to rapid climate mitigation.

Learning from war
UNSW PhD candidate Laurence Delina has investigated the rapid, large, socio-economic changes made by several countries just before and during World War 2.

He found that we can learn from wartime experience in changing the labor force and finance.

However, he also pointed out the limitations of the wartime metaphor for rapid climate mitigation:

  • Governments may need extraordinary emergency powers to implement rapid mitigation, but these are unlikely to be invoked unless there is support from a large majority of the electorate.
  • While such support is almost guaranteed when a country is engaged in a defensive war, it seems unlikely for climate action in countries with powerful vested interests in greenhouse gas emissions.
  • Vested interests and genuinely concerned people will exert pressure on governments to direct their policies and resources predominantly towards adaptation measures such as sea walls, and dangerous quick fixes such as geoengineering. While adaptation must not be neglected, mitigation, especially by transforming the energy sector, should be primary.

Unfortunately it’s much easier to make war than to address the global climate crisis rapidly and effectively. Indeed many governments of “democratic” countries, including Australia, make war without parliamentary approval.

Follow the leaders!

According to Climate Action Tracker, the 158 climate pledges submitted to the United Nations by December 8 2015 would result in around 2.7℃ of warming in 2100 – and that’s provided that all governments meet their pledge.

Nevertheless, inspiring case studies from individual countries, states and cities could lead the way to a better global outcome.

Greenpeace activists fly a hot air balloon depicting the globe next to the Eiffel Tower ahead of the 2015 Paris Climate Conference COP21Iceland, with its huge hydroelectric and geothermal resources, already has 100% renewable electricity and 87% renewable heat.

Denmark, with no hydro, is on track to achieve its target of 100% renewable electricity and heat by 2035.

Germany, with modest hydro, is heading for at least 80% renewable electricity by 2050, but is behind with its renewable heat and transport programs.

It’s easier for small regions to reach 100% renewable electricity, provided that they trade electricity with their neighbors. The north German states of Mecklenburg-Vorpommern and Schleswig-Holstein are generating more than 100% net of their electricity from renewables.

The Australian Capital Territory is on track to achieve its 100% renewable electricity target by 2020. There are also many towns and cities on programs towards the 100% goal.

If the climate action movement can build its strength and influence, it may be possible for the state of Tasmania to achieve 100% renewable energy (electricity, heat and transport) and for South Australia to reach 100% renewable electricity, both within a decade.

But the eastern mainland states, which depend heavily on coal for electricity, will need to build new renewable energy manufacturing industries and to train a labor force that includes many more highly trained engineers, electricians, systems designers, IT specialists and plumbers, among others.

Changes will be needed to the National Electricity Market rules, or at least to rewrite the National Electricity Objective to highlight renewable energy, a slow task that must obtain the agreement of federal, state and territory governments.

Australia has the advantage of huge renewable energy resources, sufficient to create a substantial export industry, but the disadvantage of a declining manufacturing sector.

There are already substantial job opportunities in renewable energy, both globally and in Australia. These can be further expanded by manufacturing components of the technologies, especially those that are expensive to ship between continents, such as large wind turbine blades, bulk insulation and big mirrors.

Chinese solar power on the waterTransport will take longer to transform than electricity generation and heat. Electric vehicle manufacturing is in the early stage of expansion and rail transport infrastructure cannot be built overnight, especially in car-dependent cities.

For air transport and long-distance road transport, the only short-term solution is biofuels, which have environmental and resource constraints.

How long would it take?
The timescale for the transition to 100% renewable energy – electricity, heat and transport – depends on each country or region and the commitment of its governments.

Scenario studies (see also here), while valuable for exploring technological strategies for change, are not predictions. Their results depend upon assumptions about the non-technical strategies I have discussed. They cannot predict the timing of changes.

Governments need to agree on a strategy for transitioning that focuses not just on the energy sector, but includes industry, technology, labor, financial institutions, governance and the community.

Everyone should be included in developing this process, apart from dyed-in-the-wool vested interests. This process could draw upon the strengths of the former Ecologically Sustainable Development process while avoiding its shortcomings.

The task is by no means easy. What we need is a strategic plan and to implement it rapidly.

Please help me with these energy, power, and work concepts?

Question by Sarah: Please help me with these energy, power, and work concepts?
Are the following true or false

-Work can be done in the absence of motion.
-Without friction or work by an external force, the sum of the potential and kinetic energies of a body is constant.
-Energy conservation law for a projectile (no friction): Potential energy increase equals the kinetic energy decrease.
-Work is done when the form of energy changes.
-More power is required while slowly lifting a box than while lifting it up quickly.
-A source of energy is required to do work.

Best answer:

Answer by omnislash
1) False, work = force x distance traveled. Without motion, there is no distance traveled and so no work done.

2) True. As long as there is no external input of force or energy, the law of COE says that the sum of KE and PE and other forms of energy in that system remains a constant.

3) True. (same as above)

4) Work IS a form of energy. Not exactly true. In ideal cases, a form of energy can change to another, not necessary work.

5) True. Power is the rate of change of energy, If I can do the same work using a shorter time, I’m more powerful.

6) True. Some form of energy is required to convert to work because energy (work) CANNOT be CREATED from naught.

4)

Writing energy conservation equation for a collision?

Question by …: Writing energy conservation equation for a collision?
For this problem, cart A is given an initial velocity towards a stationary cart B. There are pads at the end of each cart. The pads allow the carts to stick together after the collision.

Write down the energy conservation equation for this collision (Remember to take into account the energy dissipated).

right now i just have potential E(initial) + kinetic E(initial) = potential E(final) + kinetic E(final). i have no idea how to take into account the energy dissipated. any ideas?

Best answer:

Answer by E
What kind of potential energy are you tracking?

In the final state, some energy is in another form (dissipated):

potential E(initial) + kinetic E(initial) = potential E(final) + kinetic E(final) + dissipated E

where the total energy initially must equal the total energy finally.

Physics problem: energy conservation to find to find distance a block slides?

Question by A77Y: Physics problem: energy conservation to find to find distance a block slides?
An 8.78-kg block slides with an initial speed of 1.80m/s down a ramp inclined at an angle of 28.0° with the horizontal. The coefficient of kinetic friction between the block and the ramp is 0.77. Use energy conservation to find the distance the block slides before coming to rest.

Best answer:

Answer by jeffrey
Take zero gravitational potential energy GPE = 0 at the initial position …
… initial energy E₀ = ½ m v₀ ² … final energy E = – m g L sin 28° … where
L is the distance traveled along the ramp … but due to friction, energy is
removed … work done by friction W = – μ ( m g cos 28° ) L … negative
since friction is always opposite to the displacement … by conservation
of energy … E₀ = E + | W | … ½ m v₀ ² = – m g L sin 28° + μ ( m g cos 28° ) L
… ½ v₀ ² = – g L sin 28° + μ ( g cos 28° ) L …
… v₀ ² = [ μ cos 28° ‒ sin 28° ] g L
… L = v₀ ² / { g [ μ cos 28° ‒ sin 28° ] } …
Just substitute the given values to get the final answer …

Baed on the current situation, we have decided to temporarily suspend the PlayOnline service starting from March 13, 2011 at 2:00 am (PST) / at 10:00 (GMT).

Use energy conservation to find the ball’s greatest height above the ground?

Question by paperhearts63: Use energy conservation to find the ball’s greatest height above the ground?
A ball is thrown upward with an initial velocity of 16.0 m/s at an angle of 50.0 degrees above the horizontal. Use energy conservation to find the ball’s greatest height above the ground. I’m sure I’m doing this right but it told me my answer is wrong. Can someone explain how to do this? Thanks!

Best answer:

Answer by billrussell42
Getting the velocity component that is vertical, that is 16sin50 = 12.3 m/s.

Kinetic Energy in J if m is in kg and V is in m/s
KE = ½mV²
Potential Energy in J
PE = mgh
g is the acceleration of gravity 9.8 m/s²

set KE equal to PE, and solve for h
h = v²/2g = (12.3)²/2(9.8) = 7.66 meters
