1 in 5 people lack access to modern electricity, and 3 billion people still use kerosene, wood, coal, charcoal or even dung for cooking and heating (UN, 2017).

The problems with current energy consumption

Finite Fossil Fuels: The fossil fuels we have used historically, such as coal, oil and natural gas, currently the world's primary energy sources, are finite in supply. It’s not a matter of if they run out, but when: We are using them much faster than they can reproduce, formed as they are over millions of years compressing organic material. We have already passed ‘peak oil’ and at current usage it may be gone by 2052. Then switching to gas could extend just 8 further years; filling its gap with coal, that could maybe last until 2088. During that time, we may find more reserves of fossil fuels, but they’re likely smaller than the rate at which our world’s developing population is consuming them. (Source: Ecotricity)

Climate Change: Energy is the dominant contributor - burning fossil fuel emits carbon dioxide into the atmosphere, creating a man-made greenhouse effect for the world, whose insulation creates global warming and climate change. Energy currently contributes around 60% of global greenhouse gas emissions (UN, 2017), and by 2030 global demand for energy is expected to rise by 20–35% (Better Growth, Better Climate, 2014). Stabilizing global temperature will require reducing the carbon content of energy consumption, a shift to renewable or nuclear power from fossil power, significant energy efficiency and large-scale deployment of carbon capture and storage (CCS) for remaining fossil fuel use.

Energy poverty: The poorest in the world are the least likely to have access to a source of power, and are much more likely to remain poor as long as they are not connected. Poor access to energy in developing countries slows the growth of GDP, a barrier to economic growth for businesses, the most effective means of reducing poverty, yet impossible without adequate, reliable and competitively priced modern energy. Even countries with access to energy often have highly unreliable service: One in three developing countries experiences at least 20 hours of power outages a month, and when power is available, it can be expensive (World Bank, 2015).

Politics: As a result, governments subsidise demand for fossil fuels: To the tune of nearly $550 billion of public money worldwide in 2013, making energy access a political issue, and an opportunity cost for sustainable development priorities (World Bank, 2015) and capital-intensive renewables investment.

Health and Well-being: As if that weren’t enough, switching from fossil fuels to renewable and nuclear power would not only reduce the risk of climate change, but also reduce pollution, reducing mortality, disease, and ecosystem and biodiversity damage, for a healthier world

Investment: 180+ national action plans were submitted to the UN in 2015, requiring for implementation a cumulative investment of $13.5 trillion in low carbon technologies and energy efficiency until 2030 (World Energy Outlook Global Energy Trends to 2040, 2015).

To meet a 2 degree limit to global warming, the cost of electricity could rise by 30-50% by 2050. To limit the cost increase we must invest in technology innovation to lower the cost of generation and improve energy efficiency and consumption.

To decarbonise the global electricity supply, at least 65% must be generated from renewables by 2050 (PWC / International Energy Agency, Energy Technology Perspectives. Harnessing Electricity’s Potential Factsheet, 2014)

What's that got to do with Tourism?

Tourism, as one of the largest economic global sectors, is one of the largest energy-consuming sectors. Tourists also use energy (and water) with a greater intensity than local people, often to local detriment where scarcity exists.

With over a billion tourists a year set to continue increasing, tourism’s energy consumption looks only set to grow. So how hospitality gets its fuel needs provided, and how that affects and is affected by the processes of the world’s climate and ecosystem, is vital.

Tourism is both a victim of, and contributor to climate change: Rising sea levels, melting glaciers, floods, avalanches, water scarcity, deforestation, biodiversity loss, desertification, wildfires, drought and diseases hurt the tourism economy.

But these impacts are in part created by its operations, which contribute around 5-6% of global greenhouse gas emissions: 2% from aviation, around 1% from accommodations *, the rest from restaurants, activities, and other transportation. The consequences of tourism not utilising renewables can seriously impact a business, industry and world.

As such, tourism can be incentivised to help accelerate the shift toward renewable energy, increase its share in the global energy mix, help reduce greenhouse gas emissions, contribute to innovative energy solutions in urban, regional and remote areas and provide reliable energy for guests.

Customers and investors are increasingly expecting tourism businesses to be responsible and held accountable for their carbon emissions and reports. Responsible organisations voluntarily follow codes of conduct and certification schemes, such as we highlight in our Places information.

A carbon neutral travel and tourism sector has to be a long-term goal of the industry. Therefore, how do tourism businesses not create negative impacts, and preferably create positive impacts, with regards to energy?

Alternative energies for sustainable tourism and the future

Tourism and energy need not be opposed to each other: With renewables, sustainable energy and tourism can complement each other.

Sustainable energy is that which is collected from renewable sources, meaning those which are naturally replenished, such as solar from sunlight, wind, water from rain, tides, waves, and geothermal heat: natural resources which many tourism establishments are privy to.

With its large consumption of energy, tourism has a great cost incentive to utilise renewable energy for greater efficiencies and longer term cost savings – the purely economic ‘business case’ for sustainable tourism makes sense, as well as for the planet. Initial outlay may be required to change but over time works out much cheaper than previously-used energy sources. By measuring and monitoring consumption, organisations (and guests where they are aware!) can become more aware of managing consumption, efficiencies and thus longer term impacts.

Tourism is thus at the forefront of many innovative sustainable energy solutions. Whether it’s airlines making aircraft lighter, using biofuels or fuel-efficient taxi-ing, hotels saving energy with key-cards or towel reuse, or hospitality supporting local communities with energy services and related economic opportunities, the tourism industry knows it has to reduce its carbon emissions for a sustainable future. But with more than a billion tourists per year, more must be done.

What are some innovative tourism organisations doing to set the bar higher?

How Can Tourism Help?

Energy efficiency

Using less energy to perform the same task (eliminating energy waste), is often the most immediate, and cheap, way to reduce the use of fossil fuels. If we applied all the energy efficiency technologies available today, we could cut energy consumption straight away by a third (World Bank, 2015).

From 2012 to 2014, 15 of the world’s 20 largest energy-consuming countries had reduced their energy intensity — the ratio of energy used per unit of GDP. The reduction was driven mainly by greater efficiencies in the industry and transport sectors. However, that progress is still not sufficient to meet the target of doubling the global rate of improvement in energy efficiency. (UN, 2017)

There are great opportunities for using less energy in tourism and transport, eg:
-    choosing LED light bulbs and energy efficient appliances like fridges and washing machines.
-    refurbishing to upgrade heating, insulation, windows and cooling systems.
-    using energy efficient vehicles, especially electric.
-    changing standard operating procedures to decrease energy use.
-    offering incentives to guests to use less than average energy.

  • At Nikoi Island, there’s no televisions, dvds, telephones or mini bar fridges. There’s low voltage fans, LED or CFL lighting, with recycled cooking oil tiki lamps along pathways so as not to disorientate nightlife such as nesting turtles.

Energy Innovation

Continual growth in air travel due to lower costs has shown reducing emissions by reducing consumption is not likely, despite efficiency innovations to airframes, engines, aerodynamics and flight operations: Air travel is set to double every 12.5 years and emissions are projected to triple by mid-century under business as usual*.

Having said that, aviation became the first global industry to limit its carbon footprint in October 2016, as International Civil Aviation Organization (ICAO) approved a plan to offset carbon emissions growth from international flights after 2020, limiting emissions to 2020 levels from 2021.

However, the reliance on offsetting (eg. tree planting to reduce equivalent CO2 in the atmosphere) leads to effectiveness being questioned. The aviation sector is therefore actively looking at low carbon sustainable fuels to significantly reduce its climate change impact . But where land transport has alternatives (fuel cells and electric cars), aviation’s reliance is on next-generation biofuels as the only viable alternative.

Energy Generation

Despite rapid growth in recent years, renewable energy still makes up a relatively minor share of total energy consumption, growing from 17.9% to 18.3%, from 2012 to 2014, through mostly water, solar and wind power.  The challenge is to increase the share of renewable energy in the transport and heat sectors, which together account for 80% of global energy consumption. (UN, 2017)

It’s also important to balance demand and supply, in total quantity and source, eg. using more or less from wind when there's a spike in demand or little wind, balanced by alternative energy sources.

Solar: ‘Photovoltaics’ (PV) is the conversion of light into electricity using semiconducting materials. A typical photovoltaic system employs solar panels, each comprising a number of solar cells, which generate the electrical power. PV installations may be ground-mounted, rooftop mounted or wall mounted, and may be fixed, or use a solar tracker to follow the sun across the sky. Solar PV generates no pollution and no greenhouse gas emissions once installed, with simple scalability. Cells don't need direct sunlight to work – just daylight - they can still generate electricity on a cloudy day.

Low-cost small-scale solar power systems can dramatically accelerate energy access, helping countries like Bangladesh to bring energy to over 850,000 low-income households since 2003 - the largest national off-grid electrification program in the world.

  • Campi ya Kanzi only uses renewable energies, with photovoltaic panels for electricity and solar boilers for hot water, contributing to minimising carbon footprint. Energy consumption is measured and monitored monthly, with sub-meters in all guest rooms. The limited emissions that occur are offset in the MWCT REDD+ Chyulu Carbon Project with all guests charged a nominal fee for carbon generated during their stay. Carbon footprint zero is achieved. In addition, The Maasai Wilderness Conservation Trust has enabled solar power for Iltilal Primary School’s 1000 children.

  • Lapa Rios’ solar system provides for all water heating and lighting needs, as does Chumbe Island’s unobtrusive banda roof solar panels, providing charge for battery storage for energy requirements, including the office wifi.
  • At Nikoi Island, solar panels provide hot water and create an excess of energy for battery storage so that generators can be switched off 12 hours per day.
  • Jicaro Island’s solar thermal system not only allows the lodge and its guests to have hot water without the need for fossil fuel, but solar panels have also enabled the community to have electricity they didn’t have before, such as for the clean water pumps Jicaro also installed, for making the school usable after dark for adult education, and for a new community health centre.

Wind: Wind has been used for centuries for power, such as windmills to convert the energy of wind into rotational energy by means of vanes (sails) to mill grain in agriculture and pump water. Likewise, modern windmills tend to take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater.

Pangaea-Explorations Sails and wind/solar power long journeys

Pangaea-Explorations Sails and wind/solar power long journeys

  • At Lapa Rios, wind is used to cool buildings, produce power and pump water.
  • Pangaea Exploration’s sails and almost 1kw of wind/solar power long-range unsupported journeys at substantially lower cost than traditional research voyages.

When the wind isn't blowing, grid operators have to find ways to adjust:  Capturing wind's electricity as it is generated, storing and saving it for use when demand is high, could make a big difference as the technology develops. Wind farms may be spaced out so as wind shifts, one can power up as another powers down. Transmission systems now carry wind electricity from remote places with plenty of it to big cities that may be even thousands of miles away.

Hydropower: Water-powered hydroelectricity has been created since ancient times, using the power derived from the energy of falling water or fast running water, for useful purposes, such as watermills for irrigation. Whilst hydropower may not add large amounts of carbon to the atmosphere or emit pollution, dams can also have significant negative social and environmental impacts, for example altering a river’s flow, creating floods or deepening riverbeds, transforming upstream and downstream ecosystems, thus species, blocking fish migrations, affecting deltas, barrier islands, fertile floodplains, coastal wetlands and their populations. Submerged plant life can decay anaerobically (in the absence of oxygen) generating greenhouse gases like methane.

Electricity generated by hydro-electric power plants is the cheapest electricity, so it is no surprise that in 2015 hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was expected to increase about 3.1% each year for the next 25 years.

  • At Tiger Mountain Pokhara Lodge, mains electricity is used rather than an independent renewable source, as the Nepal Electricity Board mostly supplies via hydropower. However, regular power cuts mean the Lodge is forced to run a backup diesel generator.
  • At Nikoi Island, water filtering, treating and pressurising accounts for around 30% total energy use, highly efficient shower heads reduce water consumption by 20% thus energy consumption too.

Biomass: Biomass means getting energy by burning wood and other organic matter. Biomass most often refers to plants or plant-based materials that are not used for food or feed, specifically called lignocellulosic biomass.

As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel, in solid, liquid or gas form. Burning biomass releases carbon emissions, around a quarter higher than burning coal, but has been classed as a "renewable" energy source in the EU and UN, because plants can be regrown.

  • At Campi Ya Kanzi, Kenya, all food is cooked in stoves using a charcoal made from coffee husks, approved by the UN Environment Programme.
  • SEED Madagascar is supporting people to build fuel-efficient stoves to reduce pressure on protected forests and improve well-being by minimising smoke.
  • At Lapa Rios in Costa Rica, food scraps fed to pigs creates methane gas to fuel the staff kitchen stove. See this on the “Twigs, Pigs and Garbage” behind-the-scenes tour of the premises to witness the commitment to a more sustainable way of life, a unique experience so appreciated by guests it’s being replicated at Jicaro Island Ecolodge, Nicaragua!

Geothermal: Geothermal energy is the energy stored in the form of heat beneath the earth's surface. From hot springs, geothermal energy has been used for bathing since Paleolithic times and for space heating since ancient Roman times, but it is now better known for electricity generation.

With 99.9% of the planet at a temperature greater than 100°C, geothermal energy is a significant carbon-free, sustainable resource that can provide a reliable, uninterrupted supply of heat that can be used to heat homes and office buildings and to generate electricity.

Environmentally friendly, whilst geothermal wells release greenhouse gases trapped deep within the earth, the emissions are much lower per energy unit than those of fossil fuels.

Historically limited to areas near tectonic plate boundaries, geothermal energy plants are normally located in regions where there is volcanic activity, such as in Iceland. Other countries which obtain significant amounts (> 10 per cent) of their electricity from geothermal sources including El Salvador, Kenya, the Philippines, Costa Rica and New Zealand.

eEnergy Storage

Big breakthroughs have also come in the form of energy storage. New battery storage technology could see the world moving much more rapidly to at least 50% renewable energy – or even greater.

Energy efficient design

From the outset, design can make a big difference to energy consumption. For example, reducing room sizes can reduce energy use per guest night, and resorts can be designed to reduce the need for gas-guzzling vehicles.

Human Behaviour:

Places also encourage guests to change their behaviour to be more energy-wise, for example by switching off lights, quick showers to use less water, driving in a more efficient manner, and using public transport or pedal power.
