It’s estimated that even a 60% reduction in global CO2 emissions by 2050 will most certainly still result in disaster—we need 85% of emissions cut

Thirty years may seem like a long time, and the Indian government, like many others, has announced ambitious-sounding renewable energy plans

But look closely, and the current energy policy is decidedly inadequate when you account for truly liveable standards of power consumption in the future

Here’s a plan for switching to 100% clean energy—and it’s incredibly difficult no matter how you look at it. Bonus: Play with the numbers yourself, it’s all there

Questions?

What is The Ken?

The Ken is a subscription-driven media site. We write one story a day (weekdays only). These stories have sharp, original insights on technology, business, science and healthcare from India.

Why do I have to sign up to read your stories?

Our stories are not free. Well, some select stories are. But, a significant part of what we write at The Ken is for subscribers only. We put in a lot of effort and resources in writing our stories and believe that you must pay for good journalism.
Hence, our three plans. 1) The annual membership
2) The free sign up
3) The recurring quarterly subscription

On journalism and why you should pay for it, if you haven’t already seen it, here’s a great explainer from John Oliver.

So, one must pay for journalism?

Yes.

How many stories will I get if I take an annual membership?

200+ stories.

And, in the free sign up?

Four stories every month.

Do I get a refund?

We allow you to sample our journalism for free before signing up, and after you do, we stand by its quality. But we do not offer refunds.

I am not getting my daily emails. Do I have to whitelist emails from The Ken?

An added benefit of your subscription (free/paid) are the daily personalised emails. These emails, at times, might end up in your spam/junk folder due to emojis, attachments or images. In case you’re not receiving these emails, it might help to whitelist us. If the problem still persists, write to us at [email protected].

Why am I unable to access the archives?

Full and unrestricted access to our archives is a feature of our annual membership.

My payment is not going through, what can I do?

Please write to us at [email protected] detailing the payment error or queries.
