A comparative table helps you to find wich low-energy bulb or led can replace the traditional bulb and halogen bulb.
A laptop uses far less power and emits less CO2 than a desktop, but always be aware of the stand-by mode of your computer and peripherals.
Internet use means energy consumption and, therefore, CO2 production. Iinformation and communication technologies yearly account for about 4% of global greenhouse gas emissions. And this figure increases by 5 to 7% each year!
Electric cars are often presented as “non-polluting” or “zero emission” vehicles. But they are not necessarily less polluting than conventional vehicles!
A tonne of carbon dioxide is a return trip between Paris and New York by plane. In terms of volume, this represents a cube the size of a three-storey building, or 8.20 metres in edge length.
Based on data, you can easily calculate how much it costs to recharge the battery on your electric bike. Here’s an explanation.
Pellet stoves have several advantages: they are easy to use and efficient, as well as being environmentally-friendly. But they're also very expensive
A combined heat and power (CHP) system generates both electrical power and heat from a single fuel (e.g. natural gas). The system comes with a whole host of benefits. The technology was devised to serve large buildings such as hospitals. Today however, it is also available to be used in single family homes .
From now on the packaging of all light bulbs has to include an energy label. This label gives you information about the energy efficiency, the light output, the power and the lifespan of the bulb.
With a home battery, you can store electricity for later use. This is of particular interest to the owners of solar panels.
When the choice of how to heat the water is sound, the expense can change from excessive to very affordable - and very ecological...
There are three main groups of electric vehicles: fully electric, standard hybrids and rechargeable hybrids.
In Belgium, 1.7 million people use fuel oil for heating. In Brussels, 16% of all boilers operate using this type of fuel. Yet the sale of oil-fired boilers is set to be banned from 2035. Fortunately, there are alternatives
It is difficult to give a precise answer to this question. In fact, the direct and indirect CO2 emissions of your home depend on a great many parameters: the energy performance of your home, the electricity consumption, the type of heating, etc.
You can sell your green certificates at the market price to an energy supplier or an intermediary.
Everything depends on the space available on your home and the power you wish to generate.
The smart meter or intelligent meter is an electronic meter that is capable of recording and transmitting power consumption data. Smart meters will be rolled out in Brussels gradually.
Grants covering up to 50% of the bill have been agreed for three main types of work: audits, insulation, and heat recovery or production.
Electricity is the same for every home in Belgium. But if you choose a green electricity contract, your supplier undertakes to produce or buy a quantity of electricity equivalent to your consumption generated using renewable sources.
As the name implies, geothermal energy is a heating technique that exploits heat from the ground.Non-polluting, renewable and free, this energy source is of interest in the fight against global warming.
A private individual who generates power receives one green certificate per 1,000 kWh. However, a multiplication coefficient applies in Brussels. This guarantees that the installation is cost effective.
Yes it is! Combining a condensing boiler and a thermodynamic boiler allows you to harness the 2 most efficient technologies available on the market for your heating and hot water. A win-win solution for your pocket and the environment!
By adopting good habits and improving your installation, you will use less hot water and relieve your wallet.
A heat pump powered by natural gas recovers the heat that is released as part of the combustion process. Which means the appliance delivers enhanced heat efficiency that outstrips its electric counterpart and it is well placed to replace a heating boiler.
Energy labels inform you how much energy a device consumes, so that you can take this information into account when making a purchase. We teach you how to decipher them!
Nearly Zero Energy (NZE) or ‘Bijna-energieneutraal’ (BEN) is a European Directive imposed on all new buildings by 2021. However, in the Brussels Region, the even stricter passive-house standard will apply from 2015.
Regular visual inspection and servicing, every three years, by a qualified technician are sufficient for the efficient maintenance of your solar water heater and for your system to work properly.
Check the state and cleanliness of your photovoltaic panels regularly. Make sure that the installation’s cables are in good condition and that your inverter and green meter are working properly.
Four main trends can be seen at the moment: new oil and gas fields, coal, sources of renewable energy and nuclear fusion.
Your installation has to fulfil technical and regulatory conditions for you to be entitled to green certificates.
Homegrade is a non-profit association financed mainly by the Brussels-Capital Region. Its mission is to provide information free of charge for the people of the region on everything relating to their living environment, the central idea being sustainability.
In Brussels the roll-out of the smart meter is being organised by Sibelga, the power and gas distribution network operator.
In 2018, energy grants in Brussels are available for actions related to energy audits and studies, insulation and heating.
