Sustainable data centres are on the up and it is gradually reshaping the way hosting providers, like Heart Internet, power sites.&nbsp;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why Data Centre Sustainability Matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Businesses with an online presence need energy to power this. The chosen energy source behind your hosting has a genuine impact on the environment.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consumers and regulators are watching closely. There is a commitment to reducing carbon emissions in relation to electricity systems and businesses are expected to follow suit. Choosing renewable energy hosting is one of the simplest and impactful ways to lower a carbon footprint.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Makes a Data Centre Actually Sustainable? <\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A legitimate sustainable data centre goes beyond mentioning it and using logos on your website.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Renewable Energy Sourcing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Leading providers source power from wind, solar and hydroelectric generation. At Heart Internet, all hosting plans are powered by 100% renewable energy, independently verified by the Green Web Foundation.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Power Usage Effectiveness (PUE)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">PUE is the industry standard to measure energy efficiency. It compares the total energy going into a data centre to the energy being used by the equipment alone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Cooling Techniques<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cooling uses the biggest amount of energy after the servers. Modern sustainable data centres are moving away from traditional air cooling and using airflow and liquid cooling methods to cut energy dramatically.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Hardware Life and Waste Usage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sustainable operations don\u2019t just evolve around electricity. Responsible data centres invest in robust hardware with longer life and using refurbish methods and certified e-waste disposal to reduce wastage and manufacturing.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Does Going Green Mean Unreliable Hosting<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No is the simple answer.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To shift to sustainable infrastructure is proven to improve performance across the industry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Modern hardware is more efficient in design<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Better efficiency = lower energy use and better performance.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Renewable-powered data centres tend to be newer.<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The sustainability push has increased investments in new centres and green data centres are often built with the latest technology. Heart Internet delivers super fast load times and responsive performance.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Efficiency benefits all<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Smarter cooling, better power distribution reduce waste and this reduction is alike to performance optimisation. A data centre that wastes less energy also delivers more consistent and reliable web hosting.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Choose a Green Data Centre and Sustainable Hosting Provider<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you are looking at your current provider or are looking to transition, here are some questions to ask:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Is the renewable energy claim verified?<\/li>\n\n\n\n<li>Where are the servers located?<\/li>\n\n\n\n<li>What\u2019s the PUE?<\/li>\n\n\n\n<li>Does \u201cgreen\u201d come at a performance cost?<\/li>\n\n\n\n<li>Is sustainability rooted within the business?<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Green data centres are becoming the expectation for responsible businesses operating online. You don\u2019t have to sacrifice performance to get to a place of lower carbon footprints.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Renewable energy hosting has reached a level where clean power and top technology offer the best outcomes. At Heart Internet, powering your site with 100% renewable energy is all part of the package.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ready to make the switch to hosting that is better for your business and the world?
