Costa Rica achieved 99% renewable energy this year

While it may often seem like we have a long way to go when it comes to global renewable energy generation, there are a few countries that are already closing in on being fully powered by renewables that give us hope that one day soon all countries will be able to boast the same results.

Costa Rica has shown the world what is possible this year by achieving 99 percent renewable energy generation. Michael wrote back in April that the country had not used any fossil fuels for electricity so far at that point in the year and, in fact, the Costa Rican Electricity Institute said in a statement that 285 days this year were fossil fuel-free.

Costa Rica is lucky to have a wealth of renewable energy sources to choose from. The bulk of its power generation comes from hydropower thanks to a large river system and heavy tropical rainfalls. The rest is made up of a mix of geothermal energy, which the country is also rich in, wind, biomass and solar power.

The institute said that even though 2015 was a very dry year, Costa Rica was still ahead of its renewable energy targets and goal of becoming carbon neutral by 2021. The country doesn’t just want to hit 100 percent renewable energy, but it also wants to clean up energy consumption in general like moving the transportation sector away from fossil fuels and becoming less dependent on hydropower by adding more geothermal energy plants and harnessing energy from other sources.

The citizens of the country have benefited from the cost of energy actually falling by 12% this year and the institute expects it to keep falling in the future.

The U.S. still has a long way to go before it will reach the same milestones, but renewable energy plants make up most of the new energy sources being added to the grid. It’s a larger country with a larger population, but we can still be inspired by Costa Rica and do our part to make sure renewable energy grows and prospers in the U.S.

Here’s how 139 countries could run on 100% wind, solar, and hydro power by 2050

The world could be powered almost entirely by clean, renewable energy sources in the space of a few decades, and two engineers in the US say they’ve have figured out exactly how it can be done.

Blueprints for 139 countries around the world, including the US, Japan, and Australia, break down exactly how many wind turbines, solar farms, hydroelectric dams, and other facilities are required to cover each nation’s personal, business, industry, agriculture, and transport power needs, and how much it would cost. They’ll be presented to leaders of 195 nations at the 2015 United Nations Climate Change Conference (COP 21) in Paris, starting on November 30, where a binding and universal agreement on climate will be set.

The people there are just not aware of what’s possible,” one of the researchers, Mark Jacobson, a civil and environmental engineer at Stanford University, told Mark Fischetti at Scientific American. Jacobson has been granted two opportunities to speak at the conference, which will run from November 30 to December 11, and plans to get on-on-one time with as many world leaders as possible during that time with his colleague, engineer Mark Delucchi from the University of California, Davis.

The purpose of the blueprints is to show that 100 percent renewable energy isn’t just a green pipe dream – it’s technically and economically feasible. And it won’t only save countries a significant amount of cash – Jacobson and Delucchi have figured out how many jobs it could create and lives it could save, and it’s a whole lot.

As Fischetti reports for Scientific American, if all 139 countries followed their plans for permanently ditching fossil fuels, it would open up 24 million construction jobs and 26.5 million operational jobs, each with a 35-year lifespan, which more than covers the 28.4 million jobs that would be lost in collapsed fossil fuel industries.

The change would also lead to considerably cleaner air, which the engineers have estimated will prevent the 3.3 to 4.6 million premature deaths that occur every year due to atmospheric pollution. Right now, these deaths cost around 3 percent of the global GDP to mitigate.

And that’s not the only saving that a fossil fuel-free world can bring. Wind is now the cheapest source of electricity in the US, costing around half as much as natural gas – and that’s unsubsidised. And the cost of solar is not far behind.

As Ramez Naam reports over at Energy Post, if the technology continues to grow in efficiency at the current rate, by the time solar capacity triples to 600GW – predicted by around 2020 or 2021 – the unsubsidised price for solar power will be roughly 4.5 cents per kWh in places that get a lot of sunlight, such as the the US southwest, the Middle East, and Australia. For moderately sunny places, such as India and China, this price will hit 6.5 cent per kWh.

Not bad, when you consider coal-fired electricity can cost anywhere from 6.6 to 15.1 cents per kWh and it’s 6 to 8 cents for natural gas. And that’s not including all the associated health costs mentioned above.

“People who are trying to prevent this change would argue that it’s too expensive, or there’s just not enough power, or they try to say that it’s unreliable, that it will take too much land area or resources,” Jacobson told Adele Peters at Fast Company. “What this shows is that all these claims are mythical.”

The timeline states that countries could stop building new natural gas, coal, and nuclear plants, by 2020 and all gas-fired home appliances would be shifted to electric. Over the next five years, governments and industry leaders could work on getting large ships, trains, and buses off fossil fuels to run on electric power instead, followed by all cars and trucks over the next five years. By 2050, everything that currently guzzles fossil fuels could feasibly be switched over to renewable power sources.

Of course, not everyone is convinced, says Fischetti, reporting that the plans “have been heralded as transformational, and criticised as starry eyed or even nutty”, but the beauty of what Jacobson and Delucchi have put together is that everything is there for you to read through and analyse yourself, so you can make up your own mind.

3 things needed for #greengrowth: #energy, responsible resource management; good governance

Three areas are critical to achieve this: access to energy, responsible resource management, and good governance.

First, people need access to energy to leave poverty behind. But the energy sector also has a very high potential for reducing poverty while making “green” gains.
However, the electricity challenge remains daunting. In Ethiopia, with a population of 91 million people, 68 million are living in the dark. Without electricity children cannot do homework at night, people cannot run competitive businesses, and countries cannot power their economies.
This is why access to sustainable energy is a development goal in itself. According to the latest data, more poor people are gaining access to electricity at a faster rate than ever before. But the gains in renewables and progress in efficiency are too slow. Almost 3 billion still cook with polluting fuels like kerosene, charcoal and dung.
The second critical area for a sustainable and inclusive growth shift is responsible resource management.
The fishery sector, for example, holds many opportunities for smart and sustainable resource management.
A well-managed “blue” economy can ensure food security, promote sustainable tourism, and build resilience. Ineffective fish-stock management and illegal fishing waste $75 billion to $125 billion of global output annually, undermining food security and forgoing revenue.
Indonesia has more than 2.6 million fishermen. It is the world’s second-largest producer of wild-capture fish. 
If it improves governance of the fisheries sector and invests in large scale maritime transport and trade infrastructure, it can double fish production by the year 2019. 
Governance is the third area which needs urgent attention. For many countries, this is the biggest challenge.
Estimates suggest that illegal logging generates approximately $10 billion to $15 billion annually worldwide.
This is a problem of implementing existing regulations or designing better laws. And it is a global issue, rife in many resource-rich countries.
Improving transparency and monitoring is key. Government agencies often don’t know the extent to which sectors are sustainable and which natural resources are being depleted.
The energy sector, for example, needs more and better data on simple energy use and emissions. This comprehensive “green accounting” is currently lacking.
But it is also a matter of leadership, building consensus, taking on vested interests and juggling trade-offs to make the shift from ‘dirty’ and exclusive to sustainable and inclusive growth. 
So how can we overcome the obstacles to making growth sustainable and inclusive?
There are many who fear that greening growth is too expensive, could slow output, or should concern only high-income countries. This fear is short-sighted. Sustainable growth is neither unaffordable nor is it technically out of reach.
But it comes with challenges, including large up-front costs and long-term financing of 15 to 25 years. Few developing countries have suitable capital markets or banking sectors.
Improving the energy mix, for example, will reduce both environmental and fiscal risks. Turkey drastically reduced the share of oil in favor of gas. Thailand has decreased its dependency on petroleum products, from two-thirds to a third.
Another challenge is cost recovery and the right policy environment that ensures we are not only building schools, but also improve education. No power station is of use if the utility company is operating at a massive loss. Few infrastructure projects can charge at full cost. So we should find ways to ease cost recovery, while keeping services affordable for low-income families and communities.
We need to use our opportunities wisely. From 2011 to 2012, investments in clean technology in developing countries increased by 19%. And 90% of clean technology businesses increased their revenue even during the global economic downturn.
China has grown by double digits for decades, but lost a staggering 9% of its expected GDP to “brown growth.” In response, China is shifting economic activity to innovation and higher value-added production.
East Asia could take the lead on green development. Cambodia and Vietnam have integrated green growth plans into economic policies. Thailand’s most recent multi-year development plan includes a goal to reduce energy intensity by 25% by the year 2030.
Others can learn from these experiences. The good news is that more and more countries, developed and developing countries, now understand that their success will depend on how they will grow, not just by how much.
This blog is based on a speech delivered in June 2015.
