Herbert Piereder Argues Local Power is a Revolution

Published

POWER-GEN Europe and Renewable Energy World Europe Advisory Board member Herbert Piereder, Consultant Director at Applied Materials, argues that local power could completely transform the energy sector. He describes local power as a revolution with a difference – he says while most revolutions fight against states, this one depends on governments to get going. Read Herbert Piereder’s article on the local power revolution below.

There is a revolution underway. The energy industry is undergoing a radical transfer of power from the generator to the consumer. But as another famous revolutionary, Che Guevara said, “the revolution is not an apple that falls when it is ripe. You have to make it fall.”

The lesson is that revolutions can’t be left untended. People need to drive change to take place. They need to steer it to ensure the outcome is better than the status quo. This is true of the European power industry right now. Such rapid change can be tricky and governments need to do more to secure a smooth transition.

So, what is this revolution? It comes with a familiar cry of “power to the people”. Moves towards distributed and community generation are literally putting power into the hands of consumers, allowing them to produce their own energy and sell the excess back into the grid.

The timing couldn’t be any better for Europe. It’s no secret that, across the continent, countries have struggled since the financial crisis and are still seeing little in the way of GDP growth. And although energy demand has fallen in recent years due to mild winters and increased energy efficiency, Europe still needs to replace aging fossil fuel power plants and deal with the phasing out of nuclear generation in some countries.

This is an urgent concern. In 2014 alone, 13 gigawatts were removed from the European market while only eight gigawatts were added. That’s a five gigawatt net reduction in capacity in the space of a year.

And that figure just goes to show that it’s not easy to replace decommissioned baseload power plants with large-scale capital intensive installations alone. These are expensive projects to undertake and in the current economic climate, large infrastructure plans can be difficult to get off the ground.

So across Europe, power is going back to the people and going local. It has to. In fact, there are more than 5,000 energy communities in the UK alone, and the numbers are increasing across Europe as a whole.

This is welcome. Distributed generation is more secure than traditional centralised models, given that it decentralises risk and relieves dependency on large assets, the failure of which would be catastrophic. And it’s more efficient too. Community generation can act as the foundation of a more flexible power system; one that scales up or down according to demand – avoiding the production of unused energy and keeping the lights on when the supply can’t quite meet peaks.

But of course it’s not perfect. For a start, community generation is typically based on renewable generation sources like wind and solar power. And, as we all know, such sources are all-too-intermittent in their output.

So, what needs to change to make this type of distributed generation really take off? Storage for starters.

Energy storage has the potential to be the biggest breakthrough of our time. By allowing the system to hold on to our excess energy – instead of letting it go to waste – storage will play a crucial role in keeping the lights on when margins are squeezed. And it will also reduce the pressure on the sector to build more capacity into the system just to cover for big peaks in demand.

However, energy storage isn’t quite there yet. Its potential to be a game changer won’t be realised until commercial solutions are widely available. While products like the Tesla Powerwall represent real progress, governments will need to help if the technologies are to really take off. Only states can incentivise the market to develop new solutions – we’ve seen this work well for both solar and wind power. If Europe is serious about its aims for flexible power, then it must implement market levers and design schemes that support innovative technology development and its implementation.

The other big issue is the grid. The current system was designed to carry power down-the-line from large baseload plants. It simply wasn’t created with the idea of multiple inputs from decentralised generation in mind.
This century calls for a truly smart grid. But building one is no mean feat. It requires a fundamental rebalancing of the relationship between generators and networks. They will need to form closer links, communicating how the network needs to be adapt and where best to add connections.

These are real and difficult challenges. But no revolution was ever easy. This one is worth it. A flexible power system, underpinned by community generation and energy storage can provide and make use of energy on a more efficient and sustainable basis – avoiding blackouts along the way. That’s a future worth fighting for.

In addition, utilities, equipment producers, service providers, city energy co-ordinators, consultancy firms, financiers, data handlers and grid operators will share their experiences and knowledge, and discuss the industry’s current and future needs.

New Zealand to Switch to Fully Renewable Energy by 2035

New Zealand’s prime minister-elect Jacinda Ardern is already taking steps towards reducing the country’s carbon footprint. She signed a coalition deal with NZ First in October, aiming to generate 100% of the country’s energy from renewable sources by 2035.

New Zealand is already one of the greenest countries in the world, sourcing over 80% of its energy for its 4.7 million people from renewable resources like hydroelectric, geothermal and wind. The majority of its electricity comes from hydro-power, which generated 60% of the country’s energy in 2016. Last winter, renewable generation peaked at 93%.

Now, Ardern is taking on the challenge of eliminating New Zealand’s remaining use of fossil fuels. One of the biggest obstacles will be filling in the gap left by hydropower sources during dry conditions. When lake levels drop, the country relies on gas and coal to provide energy. Eliminating fossil fuels will require finding an alternative source to avoid spikes in energy costs during droughts.

Business NZ’s executive director John Carnegie told Bloomberg he believes Ardern needs to balance her goals with affordability, stating, “It’s completely appropriate to have a focus on reducing carbon emissions, but there needs to be an open and transparent public conversation about the policies and how they are delivered.”

The coalition deal outlined a few steps towards achieving this, including investing more in solar, which currently only provides 0.1% of the country’s energy. Ardern’s plans also include switching the electricity grid to renewable energy, investing more funds into rail transport, and switching all government vehicles to green fuel within a decade.

Zero net emissions by 2050

Beyond powering the country’s electricity grid with 100% green energy, Ardern also wants to reach zero net emissions by 2050. This ambitious goal is very much in line with her focus on climate change throughout the course of her campaign. Environmental issues were one of her top priorities from the start, which increased her appeal with young voters and helped her become one of the youngest world leaders at only 37.

Reaching zero net emissions would require overcoming challenging issues like eliminating fossil fuels in vehicles. Ardern hasn’t outlined a plan for reaching this goal, but has suggested creating an independent commission to aid in the transition to a lower carbon economy.

She also set a goal of doubling the number of trees the country plants per year to 100 million, a goal she says is “absolutely achievable” using land that is marginal for farming animals.

Greenpeace New Zealand climate and energy campaigner Amanda Larsson believes that phasing out fossil fuels should be a priority for the new prime minister. She says that in order to reach zero net emissions, Ardern “must prioritize closing down coal, putting a moratorium on new fossil fuel plants, building more wind infrastructure, and opening the playing field for household and community solar.”

A worldwide shift to renewable energy

Addressing climate change is becoming more of a priority around the world and many governments are assessing how they can reduce their reliance on fossil fuels and switch to environmentally-friendly energy sources. Sustainable energy is becoming an increasingly profitable industry, giving companies more of an incentive to invest.

Ardern isn’t alone in her climate concerns, as other prominent world leaders like Justin Trudeau and Emmanuel Macron have made renewable energy a focus of their campaigns. She isn’t the first to set ambitious goals, either. Sweden and Norway share New Zealand’s goal of net zero emissions by 2045 and 2030, respectively.

Scotland already sources more than half of its electricity from renewable sources and aims to fully transition by 2020, while France announced plans in September to stop fossil fuel production by 2040. This would make it the first country to do so, and the first to end the sale of gasoline and diesel vehicles.

Many parts of the world still rely heavily on coal, but if these countries are successful in phasing out fossil fuels and transitioning to renewable resources, it could serve as a turning point. As other world leaders see that switching to sustainable energy is possible – and profitable – it could be the start of a worldwide shift towards environmentally-friendly energy.

Increasing your home’s energy efficiency is one of the smartest moves you can make as a homeowner. It will lower your bills, increase the resale value of your property, and help minimize our planet’s fast-approaching climate crisis. While major home retrofits can seem daunting, there are plenty of quick and cost-effective ways to start reducing your carbon footprint today. Here are five easy projects to make your home more sustainable.

1. Weather stripping

If you’re looking to make your home more energy efficient, an energy audit is a highly recommended first step. This will reveal where your home is lacking in regards to sustainability suggests the best plan of attack.

Some form of weather stripping is nearly always advised because it is so easy and inexpensive yet can yield such transformative results. The audit will provide information about air leaks which you can couple with your own knowledge of your home’s ventilation needs to develop a strategic plan.

Make sure you choose the appropriate type of weather stripping for each location in your home. Areas that receive a lot of wear and tear, like popular doorways, are best served by slightly more expensive vinyl or metal options. Immobile cracks or infrequently opened windows can be treated with inexpensive foams or caulking. Depending on the age and quality of your home, the resulting energy savings can be as much as 20 percent.

2. Programmable thermostats

Programmable thermostats have tremendous potential to save money and minimize unnecessary energy usage. About 45 percent of a home’s energy is earmarked for heating and cooling needs with a large fraction of that wasted on unoccupied spaces. Programmable thermostats can automatically lower the heat overnight or shut off the air conditioning when you go to work.

Every degree Fahrenheit you lower the thermostat equates to 1 percent less energy use, which amounts to considerable savings over the course of a year. When used correctly, programmable thermostats reduce heating and cooling bills by 10 to 30 percent. Of course, the same result can be achieved by manually adjusting your thermostats to coincide with your activities, just make sure you remember to do it!

3. Low-flow water hardware

With the current focus on carbon emissions and climate change, we typically equate environmental stability to lower energy use, but fresh water shortage is an equal threat. Installing low-flow hardware for toilets and showers, particularly in drought prone areas, is an inexpensive and easy way to cut water consumption by 50 percent and save as much as $145 per year.

Older toilets use up to 6 gallons of water per flush, the equivalent of an astounding 20.1 gallons per person each day. This makes them the biggest consumer of indoor water. New low-flow toilets are standardized at 1.6 gallons per flush and can save more than 20,000 gallons a year in a 4-member household.

Similarly, low-flow shower heads can decrease water consumption by 40 percent or more while also lowering water heating bills and reducing CO2 emissions. Unlike early versions, new low-flow models are equipped with excellent pressure technology so your shower will be no less satisfying.

4. Energy efficient light bulbs

An average household dedicates about 5 percent of its energy use to lighting, but this value is dropping thanks to new lighting technology. Incandescent bulbs are quickly becoming a thing of the past. These inefficient light sources give off 90 percent of their energy as heat which is not only impractical from a lighting standpoint, but also raises energy bills even further during hot weather.

New LED and compact fluorescent options are far more efficient and longer lasting. Though the upfront costs are higher, the long term environmental and financial benefits are well worth it. Energy efficient light bulbs use as much as 80 percent less energy than traditional incandescent and last 3 to 25 times longer producing savings of about $6 per year per bulb.

5. Installing solar panels

Adding solar panels may not be the easiest, or least expensive, sustainability upgrade for your home, but it will certainly have the greatest impact on both your energy bills and your environmental footprint. Installing solar panels can run about $15,000 – $20,000 upfront, though a number of government incentives are bringing these numbers down. Alternatively, panels can also be leased for a much lower initial investment.

Once operational, a solar system saves about $600 per year over the course of its 25 to 30-year lifespan, and this figure will grow as energy prices rise. Solar installations require little to no maintenance and increase the value of your home.

From an environmental standpoint, the average five-kilowatt residential system can reduce household CO2 emissions by 15,000 pounds every year. Using your solar system to power an electric vehicle is the ultimate sustainable solution serving to reduce total CO2 emissions by as much as 70%!

These days, being environmentally responsible is the hallmark of a good global citizen and it need not require major sacrifices in regards to your lifestyle or your wallet. In fact, increasing your home’s sustainability is apt to make your residence more livable and save you money in the long run. The five projects listed here are just a few of the easy ways to reduce both your environmental footprint and your energy bills. So, give one or more of them a try; with a small budget and a little know-how, there is no reason you can’t start today.
